Any clues or example codes about how to use nrf51822 with sx1276 for lora?

[delancao]

Currently, I am trying to run the semtech lorawan code on nrf51822 with sx1276. I have successfully porting the ping pong code to nrf board and also able to send packets from the board to the semtech server, but I am stacking in the receive part. Anyone has some clues how to receive lora packets from the servers? By the way, I have already found a example code which based on mbed lib, but according the requirements, I won't use the third parties lib but only the nrf51 sdk.

Is this LoRaWAN you are talking about? Or pure LoRa? Are you saying that you have ported LoRaWAN stack to NRF51 or just using LoRa PHY?

I might be of help, but please be more specific about your issue. Also - do ou have any code to share?

LoraWAN, I have porting the LoRaWAN to the NRF51, and tx function is working, but rx is not working.

Hi, did you manage to run LoRaWAN stack simultaneously with BLE softdevice? Looks like default Semtech implementation does not fit int RAM when running with softdevice. Also, I am still struggling to put together softdevice control loop with lmic control loop in order to get to ultra-low power mode between LoRa transmission while maintaining BLE responsive.

january 2018: RAKwireless has a new module RAK813 combining nRF52832 with SX1276 and - THANKS to RAK! - ported the LoRaWAN stack.

The github project is called RAKWireless/RAK813-BreakBoard
