I have an AS923 RAK 5205 and I am using the recommended RAK Serial Port Tool. However, any AT command I sent only prompts an “ERROR: 86” message, which corresponds to “The device has not joined a LoRa network” based on the AT command manual.
I don’t have a gateway that supports AS923 currently, which is why I am trying to change the region of the RAK 5205 device using “at+set_config=lora:region:US915”
I am quite confused about why this is even happening because AT commands are simply serial commands and shouldn’t require the device to join a LoRa network. How can I debug this?
