I have been able to transmit with my sensors from an Arduino UNO to another UNO using the HC12's. I have set the AT8 command for highest xmot power level but can only get about 7 feet before it looses connection. I am only using the stubby wire antennas. Is there a better antenna (specific model please) that will work with these units or am I doing something wrong?
I eventually have to have my sensors transmit from outside the house to the display inside. Will these work?
I also have the 2.4GhZ (NRF24L01's) units but cannot get those to work at all.
Any help would be appreciated.
