I have a RAK811 module that seems like it has old firmware on it. at+version
gives OK2.0.3.0
. Many other commands, for example at+set_config=device:restart
give various errors.
I think that perhaps this old version of firmware doesn’t support many of the newer commands. I would like to upgrade it to version 3.0.0.14 and have tried to use the RAK Device Firmware Upgrade Tool v1.4. to do this. However, this results in a timeout every time I try.
For reference, the module I have has P/N: RAK811-868MHz and LOT number: 201919 printed on it, rather than RAK811(H) and the module also does not have the DevEUI printed on the outside.
My question are:
- Can I safely upgrade this part to firmware version 3.0.0.14?
- If I can safely upgrade this part’s firmware, how do I do it? I am happy to update the bootloader via SWD / STMCube32Programmer if needed, but I want to check that the hardware I am using is compatible.
Many thanks in advance
