I struggle to get my rfm69hw to talk to eachother. And im running out of ideas. This is the log what i was doing, so maybe someone else got same symptoms.
First nano is 5V and rfm69 works on 3,3V. Nano has 3,3 power source and i used it to power rfm69 chip, but logic gates where on 5V.
Soldered all the wires and booted them up with standard gateway and node example, nothing happens first. Then i thought maybe some wires are loose and keep checking. Weirdly enough, connection established when i touched gateway ground and 5V power with my hands. got RSSI around -50 while they keep a meter apart. Thought, maybe its because 3,3v-5v communication is failing and got some logic converters. soldered them between and tested again. No connection. Got separate 3,3 power source from a shield, exact same result.
So i thought, lets check if communication works between arduino nano and rfm69. Sended 'r' command trough serial port and got registers. Gateway seemed ok, node sended only 1-s. Seemed wiring problemm - replaced whole rfm69 chip and got node working with registers.Tested A2 port with sending high in it, both react but there is no data to transfer. i concluded, that wiring must be correct on both boards.
So i now need bit of help to test where the problem could be. Is there a way to test if antenna is sending something. And ig gateway is registering anything? ideas?
