Secondary ESP8266 gateway

I'm finding it odd as well that PA LNA also fails to connect from that distance. I only had these two - one on the gateway and the other now on the hive sensor. The rest are all regular pcb antenna versions. I've ordered 5 more PA LNA versions just to be sure it's not a faulty radio.
That means another month of waiting for them to arrive though...

Guess we can mark this one down to iffy PA/LNA modules. After verifying that a repeater solves the problem, I replaced both, the gateway and beehive sensor radios out for regular nrf24l01's. At first I had a repeater as well in between the two, but after making sure the communication was there, I disconnected the repeater.
And lo and behold - the communication still works fine. So now I modified the gateway radio by cutting the pcb antenna trace and soldering in a SMA connector. Now I have a high DBi wireless antenna attached to the gateway and no more reception issues.

I'll see if wrapping them in tin foil helps any.

The tin foil wrap tip should definitely be mentioned on the radio page. That trick really works wonders. I used ventilation aluminum foil tape. The glue on it acts as insulation so no need to use food wrap. It's also thicker than regular food grade tin foil and it being a tape makes it super easy to use.
