Hello @EliotBR,
I tried to upload firmware and even its written successfully it is not. I checked ardusub firmwares and i could not see any stable firmware for cube orange plus. Then i decided to take a new cube orange and i solved the problem. Everything is fine right now but in the future i’d like to use cube orange plus also. I will wait for the stable version of Cube Orange Plus to be shared.
As you can see here, There is no stable version of Cube Orange Plus. There is only Cube Orange ones.
