- First SMS from any number becomes the primary number
- If no allowed numbers configured, all numbers are allowed
- If no call numbers configured, no calls will be accepted
- All commands are case-insensitive
- Invalid commands will receive error response
- RESET command works from any number but requires IMEI
- WiFi location is optional and disabled by default
- WiFi networks are sent to server when GPS is unavailable
- Red: GPS status
- On: GPS locked
- Off: GPS disabled
- Blinking: Searching satellites
- Blue: Network status
- Off: No server configured / No internet
- Blinking: Connecting to server
- Pulse: Data transmission
- Yellow: Battery status
- On: Normal operation
- Blinking slow: Charging
- Blinking fast: Low battery (<20%)
- Blinking very slow: Sleep mode
- Main chip: Quectel EC800N-CN (LA)
- System: MicroPython v.1.13.0 (mPY: 10245, Python v3.4.0, QPY v0006)
- mPY RAM: 512256 bytes
- mPY ROM: ~576KB in /usr/ plus ~100KB in /bak
- GPS Chip: AT6558 Datasheet
- Microphone is preset, but there is no voiceCall class in firmware, so we can't accept or make calls
- Power button connected to dedicated power IC. Short press - poweron, long press (10+ seconds) - poweroff.
- Reset button just reset power of device.
- i2c0 have two devices on address: 0x62 and 0xE2. Can't understand, what is it. Maybe its i2c interface of GPS module (there is no info in datasheet)
