Hello!
I use SX1262 + STM32 with LoRaMAC stack.
The software work fine with NUCLEO STM32L476 + SX1262MB2CAS shield.
I made my own RF-module with the SX1262. And the same code does not work with NUCLEO STM32L476 + my module. The device is not connected to the network.
BUT!!!
As soon as I disconnect the VR_PA from the RFO pad, the device starts working! RSSI is around -90, but the device work stably!
Restoring contact leads to loss of communication again.
I have checked all possible short circuits and breaks of these circuits. And everything is fine. The nominal values of the components (2 Cap and 1 Inductor) correspond to the shield or are slightly different.
Why can this happen? I don’t have any ideas left. I can’t accept with -90 RSSI.
