nRF52840 with Lora transceiver SX1276 or SX1261 or SX1262

[james]

we are entertaining the idea of using an nRF52840 with a Semtech SX1276 (or possibly SX1262) as a BLE/LoRa endpoint node. We believe this is doable but wanted to make sure that we were not going in the wring direction. thank you

Planning to use the Nice RF LoRa1276-C1 module since it is already certified.

Ok, Good.

And you want to connect it with NRf52 series ?

I couldn't find ready stack for nrf52+sx1267x except the one from RakWirelss.

As haakonsh said, the Semtech chips just have an SPI interface to the controller.

Semtech provide reference code - so, as ever, the only Nordic-specific bit would be the detail of driving the SPI hardware peripheral.

if you look at, say, ST's LoRa stuff you will see that it is based on the Semtech code ...

Note that mbed has recently released their LoRaWAN 1.1 stack:
