Here's an unusual question: Is it possible to disable the radio?
I've got a device that's got a radio soldered on to it so it's not possible to unplug it. But I'm not using the radio so I'd like to leave the antenna off but I don't want to risk damaging the amplifier. So, is there an AT command that would allow me to do this? It looks like you set TXPOWER to 0 but if you do this, is it then safe to disconnect the antenna?
