• ST: 0.5E

Please refer to the instructions in this article for sending the commands. After the command is sent, please refer to points (3) and (4) of Scenario 1 for details about the operation of the device.

Note: Each parameter value at this time is not the default value but the value set by the mobile app.

Indicator Light State

• If USB power is connected and the normal electric quantity is above 20%, the indicator light will be steady green.
• If USB power is not connected or the electric quantity is abnormal, the indicator light will quickly flash red.

FAQ

• Q: Can I use the device without enabling the occupied sensor?
• A: No, the occupied sensor must be enabled for the device to start.
• Q: What happens if I get up while the equipment is inflating?
• A: The equipment inflating operation will stop if you get up midway during inflation.

Scenario 1 State

1. The user needs to sit on the occupancy sensor.
2. When the occupancy sensor operation is detected, the device inflation operation is initiated
3. After the occupy sensor is working， PSI is defaulted to 1.8。 Let’s start with the odd side （1、3、5、7）inflate， After inflation reaches 1.8 PSI， The valve holds this pressure value for 0.5 minutes by default， after 0.5 minutes， odd edge（2、4、6、8） starts passive air transfer， transfer default 10 seconds。 After 10 seconds of transmission, the PSI value is detected. If the PSI value is 0 at this time, the same charging and deflating action is carried out on the even edges (2,4,6,8) according to the above default values
4. If the occupy sensor works, the device repeats the alternating pressure cycle. Otherwise, the device does not repeat the alternating pressure cycle.

Scenario 2 State

1. The user needs to sit on the occupancy sensor.
2. app need send command，like（SP:2.5E SK:0.5E ST:0.5E）these three command send to MCU。Please see the instructions in this article.
3. For details about the operation of the device after the command is sent, refer to points (3) and (4) of Scenario 1， At this time, each parameter value is not the default value, but the value set by the mobile App

Occupy sensor State

1. Regardless of whether the working mode is Scenario 1 or Scenario 2, the occupied sensor must be enabled; otherwise, the device cannot be started
2. When the equipment is inflating, if the user gets up midway, the equipment inflating operation stops.

10. Update RTC
    After the completion of the upgrade of the device default run 00 years 00 months 00 days 00 hours 00 minutes 00 seconds, need to be adjusted through the app, the app needs to send instructions as follows W:23:07:25:10:30:08 This instruction corresponds to the hexadecimal number 0x57,0x3a,0x32,0x33,0x3a,0x30,0x37, 0x3a, 0x32, 0x35, 0x3a, 0x31, 0x30, 0x3a, 0x, 0x33, 0x30, 0x3a, 0x30,0x38 This command means to change the current RTC time to July 25, 2023, at 10:30:08 AM Please reflect all data digits as even numbers.，For example, in July, a 0 should be added in front of the number 7 to change it to 07, and 8 seconds should be added in front of a 0 to change it to 08 seconds, because MCU needs to receive hexadecimal data, and the data bit format should be sent in the form of an even number. Please send the data to MCU 1 second in advance of the setting time, and MCU will return the OK command to the App after receiving the command successfully.

11. Launch Scene 2
    App needs to send three commands, there is no requirement for the order of commands to be sent, but the three commands must be sent, and the commands need to be sent completely without error, otherwise, the MCU refuses to receive the command. These three commands, such as SP:1.8E SK:1.0E ST:0.5E Each of these three instructions correspond to a hexadecimal number of 0x53,0x50,0x3a,0x31,0x2e,0x38,0x45 0x53,0x4b,0x3a,0x31,0x2e,0x30,0x45 0x53,0x54,0x3a,0x30,0x2e,0x35,0x45 Where the first hexadecimal data is the start code, the MCU will not start receiving the later data until it receives 0x53, and will not start to end receiving the data until it receives the end code 0x45, and all the data should be accurate, otherwise the data is invalid.

These three commands are explained as follows SP:1.8E The 1.8 in the data represents that the PSI is set to 1.8. 1.0 in the SK:1.0E data represents that the valve exhausts for 1×10=10 seconds, and then for example, the 2.5 in the data represents that the valve exhausts for 2.5×10=25 seconds. 0.5 in the ST:0.5E data represents that the PSI is maintained at the value hold time of 0.5×60=30 seconds, and then 1.0 represents maintaining that PSI value hold time of 1.0×60=60 seconds. The legitimacy of these data is limited to those provided in the previous development documents (0.5,1.0,1.5,1.8,2.0,2.5,2.8,3.0), and data not declared in the development documents are invalid. When setting the parameters, please fill in the data strictly according to the data provided in the development document.

Attention

1. the parameters set by these three commands only support (0.5, 1.0, 1.5, 1.8, 2.0, 2.5, 2.8, 3.0), these data are provided by the development documents, the parameters set please enter according to these data, other data is invalid.
2. Don’t send each instruction at the same time, please send one instruction at an interval of 500 milliseconds.
3. MCU will return the OK instruction to the App after receiving the instruction successfully.
4. If you need to adjust the parameter, you can send the accordingly command. No need to send three commands together.

Low Power Mode (Shutdown Command)

• The app needs to send command w: SD to MCU, This instruction corresponds to the hexadecimal number 0x77,0x3a,0x53,0x44, the instruction must be sent in full, otherwise, it can not enter the low-power mode The MCU will return the SD command to the App after receiving the command successfully.
• Query one month’s data method（It takes about 15 minutes to complete the query and return the data to the app if the data is available for that month.） The device records data every 1 hour and has a data storage capacity of 12 months. The order of data storage is Year, Month, Day, Hour, PSI, Occupancy Open Time, Occupancy Close Time, Valve Hold Time, Valve Close Time, and Battery Power Percentage, totalling 10 recorded data. There is no need to delete the data when it is full because the data for each time of each day of each month of the 12 months of the year has a uniquely determined address, and the data storage will store the data for each moment to the uniquely determined address. If last year’s data is stored in a particular address area, it will be overwritten by this year’s data. For example, if you start storing data at 1:00 on January 1, 2022, there are 10 members of the hourly data, which are stored in address 0, and the 10 members of the hourly data at 2:00 on January 1, 2022, are stored in address 1, and so on for each hourly data storage address. The 10-member data in these hours are stored in uniquely determined addresses until the next year’s corresponding hourly hour is stored, and the data for the corresponding hour of the previous year is not cleared and overwritten.
• The app needs to send commands like C: ALL:7E to MCU The hexadecimal number corresponding to this instruction is 0x43,0x3a,0x41,0x4c,0x4c,0x3a,0x37,0x45 This command means to query all the data available in the July record and give the data to the app. Parameters are only allowed to be entered (1,2,3,4,5,6,7,8,9,10,11,12). Parameters must not be in the form of an even number of digits, except for October, November, and December. For other months, please input the month parameter data directly, and it is forbidden to make up 0. When MCU receives the command successfully, it will return the OK command to the app.
• After receiving the complete command, the MCU first parses the data for July to see if it exists, and if it does, the app will receive the year:23 Note：2023 Year month:07 Nore：07 month day:25 Note：25 day hour:10 Note：a.m.(10-1)=9 hour P:1.5 Note： The data P:1.5 indicates that the PSI value at that time was set at 1.5 occupy on:35 Note： Show the recorded time of occupancy,35 minutes occupy off:25 Note： Shows the non-occupied time recorded at the time,25 minutes valve on:30 Note: Show the time recorded for the valve to maintain pressure at that time,30 seconds valve off:60 Note: Show the valve exhaust time recorded at that time,60 seconds B:68 Note: The electricity level was 68% Once the query is over, then the app will receive instructions such as F:102， This command represents a total of 102 messages queried for that month’s data
• Erase the whole flash (the user should not operate, otherwise the machine will not work normally) The app needs to send the command f: erase to MCU, the corresponding hexadecimal number of the command is
• 0x66,0x3a,0x65,0x72,0x61,0x73, 0x65, this instruction can only be used once when the manufacturer factory upgrades the program, do not operate at any time, otherwise, it will lead to the loss of all data! Please wait for 1 minute…… the device does not work properly, after the operation, the app will receive the message Please wait for 1 minute!
• Erase successful message will be sent to you. Otherwise, the app will receive a Prohibit operation Flash message.

app command receive

1. Turn on the prompt command. （UP） When the device is normal, the app will receive commands every 1 second UP
2. Charge full command（FC） When the battery is full the app will receive a command FC
3. The low battery alert（LBL） App receives a command when the battery is too low LBL
4. Successful data saving prompt（DSS） When the data is saved successfully the app will receive the command DSS
5. Inflation Abnormal Alert（ED、AG） App receives instructions when an abnormality occurs during the inflation process ED or AG

The reasons for the abnormality are as follows

1. PSI value is detected to be abnormally high
2. Inflation time up to 90 seconds PSI value has not reached the set PSI value
3. The detected air pressure value is higher than the set PSI value when inflation starts. Please check whether the air tube or pump is normal, whether the line is in good contact, and whether the MCU is working normally.

Gas Leakage Notification（GL）

• A gas leak is indicated if a PSI value of <0.2 is detected during the time that the device maintains a hold of air pressure， The App receives the command GL

PSI error notification（LT）

• The time that the equipment is maintained at a maintained air pressure If PSI<PSI-0.2 or PSI>PSI+0.2， Then the air pressure value error is large and the App will receive the command LT

Appendix

1. About RTC, to ensure that the database data storage is normal, please ensure that the button battery stable power supply, and from time to time to check the device RTC time, if the device running time is not normal, please adjust in time. （It is recommended that when the mobile app is connected, the app automatically sends a time update command to the MCU for time calibration）
2. Due to the electrical level jitter caused by the mechanical nature of the silicone key, it is recommended to press the silicone key for 1 second to inflate the start and stop
3. If the software has requirements for the inflation order of inflating odd and even sides, it can be adjusted by simply exchanging the control interfaces of the two valves.
4. Regarding the power level, when the power level is lower than 20%, the MCU operates normally, but the pumps and valves may not operate normally, at this time, if you start the device to inflate, the device will automatically terminate inflation within 20 seconds, and accompanied by a red light flashing rapidly, please recharge the device in time when the power level is lower than 20%
5. When the device is switched on and off, whether it is closed by the App or closed by the silicone button, please turn it on again after 5 seconds. Because of MCU in the closed equipment, need to store data, and refresh data, disconnect the power operations such as, need some time!
