I know this is a Semtech bug, and not a Nordic issue, but I am posting here in case it helps others, or someone has fixed it.
Semtech have a new LoRaWAN platform called "LoRa Basic Modem" and have a port for the nRF52840. I have tried to build this with the SX1262 radio modem but the compilation fails since they are using hal_spi_in_out() incorrectly, with too few parameters. I have raised this issue with Semtech.
Has anyone tried to use the nRF52840 & SX1262 combination, either with the "LoRa Basic Modem" platform or the earlier LoRaMac-node platform?
IMHO the pairing of the nRF528xx plus SX16x is a great combination for IoT devices (BLE plus LoRaWAN), and there is a need for a robust open source port...
