LED Indication
Battery Indication
When the device runs in recycling mode, press its function button ⑤ for 3
seconds and the power LED ② will light on for 4 seconds to tell you the
strength of the internal battery.
| LED Status | Battery Strength | Min. standby time |
|---|---|---|
| 4 LEDs on | 80% to 100% | 1550 days |
| 3 LEDs on | 50% to 79% | 950 days |
| 2 LEDs on | 30% to 49% | 550 days |
| 1 LED on | 10% to 29% | 190 days |
| 1 flashing LED | 1% to 9% | Exhausting |
Note:
The min. standby time is estimated on the ground that the device generates one
fix per day.
GNSS Indication
The GNSS LED ③ is used to show the working status of the device’s GNSS module, where:
- Flashing rapidly [on–off (0.1s–0.1s)]: The device is searching for satellite signals;
- Always on: A position has been fixed;
- Off: The GNSS module isn’t working.
Cellular Indication
The cellular LED ④ is used to show the network status of the device, where:
- Flashing slowly [on–off (0.1s–0.5s)]: The device is identifying the SIM card;
- Flashing rapidly [on–off (0.1s–0.1s)]: The device is receiving cellular signals;
- Flashing slowly [on–off (0.1s–0.1s)]: The device is online;
- Off: The device fails to receive cellular signals or no SIM card is identified.
Configuration
APN Setting (If no network is available, you are advised to set the
APN via the mobile app – JIMI IoT LAB)
Command: APN,
N: Network name
U: User name
P: User password
Note: The parameters “U” and “P” can be left empty. The command is
“CMNET#” by default.
APN adaptation switch: ASETAPN,
SW: Switch to enable or disable the APN adaptation feature, whose value is
either “ON” or “OFF”.
Note: The default value for “SW” is “ON”. Comparing these two setting
methods, the priorities of manually-set APNs are higher than the self-adapted
ones. Once an APN is manually changed (via a command sent by the user), the
adaptation feature will turn invalid (auto switched to OFF). This auto switch-
off protects the device against failing to go online in the event of an APN
recognizing failure or an incorrect APN.
Working Modes
Recycling mode (Mode1)
In recycling mode, the device will disable the cellular and GNSS modules,
which means it will neither fix positions nor upload location data.
Standby mode (Mode2)
In standby mode, the device uploads a position fix every 24 hours by default.
You can change the interval and time point of upload via a command delivered
by the platform or via the Jimi IoT LAB mobile app.
Set command:
MODE,2,Time,Interval#
Time: 00:01 to 23:59 (default: 07:00)
Interval: 60 to 1440 (default: 1440 minutes)
Tracking mode (Mode3)
In tracking mode, the device uploads a position fix every minute. You can
change the upload and positioning duration via a command delivered by the
platform or via the Jimi IoT LAB mobile app.
Set command:
MODE,3,interval,Working Time#
Interval: 60 to 360 (unit: seconds; default: 60 seconds)
Working Time: 0 to 1440 (unit: minutes; default: 10 minutes)
Note: If the working time is set to “0”, the device will not exist
tracking mode.
Switching Modes
Switch by command:
MODE[,A]#
A: 1 for recycling mode, 2 for standby mode, 3 for tracking mode
Query current working mode:
MODE#
Switch by key press:
- If the device is in recycling mode, press the function button ⑤ for 5 seconds to switch to standby mode;
- If the device is in standby mode, short press the function button ⑤ for 3 times in 5 seconds to switch to recycling mode.
