Hi Joe S.,

the modules are connected directly to the pics.

One thing i noticed and i found it weird is that when turning the power on the receiver ( and always the RX - never happened to the TX ) sometimes does not start receiving ( although the TX is transmitting ).

My workaround is to turn power off for a couple of seconds and reconnect power ( and sometimes i have to do this 2 or 3 times ).

I changed modules, experiment board, etc and this only happens on the RX side.

Should it be any startup procedure sequence for the RX ?
