Issue:RAK5205 GPS is not working
Setup: Firmware Version: RUI v220.127.116.11.H.T1
Hello, I need help and / or support.
I have bought a RAK5205 module a few months ago. I have recently tried to use it but find that the GPS is not working. This can be seen in the following copy of the RAK serial port tool:
Start Search Satellite(about 300 seconds) …
FAIL.The Satellite signal not found!
*Battery Voltage = 4.193 V *
BME680 sensor data:
- Humidity:39.89 %RH*
- Temperature:32.94 degree*
- Pressure:852.63 hPa*
- Gas_resistance: 23481 ohms *
LIS3DH sensor data:ACC_X: 86mg, ACC_Y: -74mg, ACC_Z: -1008mg
[LoRa]: send out
[LoRa]: RUI_MCPS_UNCONFIRMED send success
I have configured the GPS with the following instruction to avoid sleep mode:
at + set_config = lora: send_interval: 2: 60
On the other hand, reviewing the schematic diagram I find that some components are apparently not installed, for example: C52, L2
You can also see the poor technique of the soldering of the antenna connectors!
See attached image for reference.
