JDY-19 Ultra-low Power Consumption Bluetooth 4.2 Module

Product introduction

JDY-19 transparent transmission module is based on the Bluetooth 4.2 protocol standard, the frequency range is 2.4GHZ, the modulation mode is GFSK, the maximum transmission power is 4dB, the maximum launch distance is 40 meters. The imported original chip is designed to support the user to modify the device name, baud rate and so on through the AT command, which is convenient, quick and flexible to use.
JDY-19 Bluetooth module can realize data transmission between module and cell phone, or module and module, and can quickly use BLE Bluetooth for product application through simple configuration.

Let BLE be more quick and convenient in product application

transmission current is 900uA, and the disconnect current is below 200uA (the broadcast interval current can be set to 30uA). After the PWRC pin wake-up under this mode, if the serial port does not send data in 10 seconds or not to be connected, it will turn into sleep again automatically.

3.4 Frequently asked questions

I : How MCU disconnects the
Bluetooth connection in the
connection state?| In the connection state, lower the PWRC pin, and the serial port sends AT+DISC to disconnect.
2:How much is the current when the module wakes up?| All modes’ working current Is not more than 1 mA.
3:How many data can be written to the serial port once?| No byte limit at 9600 baud rate
4:After the serial port is configured, is it need to restart to take effect?| It is recommended to restart the module when the parameters are set
5:How to test the deep sleep current of the test module?| VCC and GND pins are recommended for testing current.

AT instruction introductions

Special description: JDY-19 module serial AT instructions need to end with \r\n
Query – version number

Setup – soft reset

Set up – disconnect

Note : Under connection state, the PWRC pin needs to be pulled down to send AT instructions in the connection state.
Setup/query – MAC addresses

Setup/query – baud rate

Setup/query – sleep instruction

1:Light sleep (Broadcast)
2:Deep sleep (No broadcast)
AT+SLEEP

AT+STARTEN0 state does not need to send AT+SLEEP instructions, modules automatically enter sleep. After the mobile phone is connected, it will wake up automatically, if disconnecting the connection it will automatically turn into sleep. PWRC pin low level wake-up, it will automatically go to sleep if the serial port has no data transmission, or no connection after wake up 10 seconds later.

Setup/query –broadcast name

The longest: 18 bytes
Default name: JDY-I9
AT+NAME| +NAME=

Setup/query – start sleep and wake-up read & write

1: Start wake up, sleep can be controlled by AT+SLEEP
0: Start sleep, connect to wake-up,
disconnect to connect sleep
AT+STARTEN| +STARTEN=

Setup/query – broadcast interval

Setup/query – Module working mode

0—Slave ( APP, WeChat small
program) transparent transmission
3—Slave ( iBeacon) mode
Default value: 0
AT+HOSTEN| +HOSTEN=

Setup/query – iBeacon UUID

AT+IBUUID| +IBUUIDParam>

Example：AT +IBUUID FDA50693A4E24FB1AFCFC6EB07647825
Setup/query – iBeacon Major

If the Major value is 10008, the AT instruction is: AT+MAJOR2718 2718 is 10008 hexadecimal data.
Setup/query – iBeacon Minor

If the Minor value is 10180, the AT instruction is: AT+MINOR27C4 27C4 is 10180 hexadecimal data.
Setup/query – iBeacon IBSING

This parameter is applied to the 1 meter iBeacon signal check value
