Unable to use LoRa library after LoRa FW update

Official Hardware MKR Family MKR WAN 1310
1

Hi all,

I've updated the firmware of the LoRa module using the MKRWANFWUpdate_standalone sketch from the MKRWAN_v2 library to version 1.3.0.0 .

Before doing so the examples from the LoRa library (https://github.com/sandeepmistry/arduino-LoRa) worked fine. After updating I get the message "Starting LoRa failed!". This message is triggered by the LoRa.begin(frequency) function (as per the examples).

void setup() {
  Serial.begin(9600);
  while (!Serial);

  Serial.println("LoRa Receiver");

  if (!LoRa.begin(915E6)) {
    Serial.println("Starting LoRa failed!");
    while (1);
  }
}

In this function there is the following piece of code:

  uint8_t version = readRegister(REG_VERSION);
  if (version != 0x12) {
    return 0;
  }

The contents of version is 0xFF...

I've tried to downgrade the firmware to various versions (1.1.6, 1.2.0) but I did either didn't do it properly (I've downloaded the 1.1.6 fw.h from github via the history option) or I've got to do something else entirely.

How can I solve this?
