OMG on esp32 with rfm69


After some issues and lot of time spend I have a working gateway connected to my Home assistant broker and able to send data from mqtt to rfm69.
Ack is received after sending data.
But when I want to read data on receiver side it tell me datalen is 0.
data send is {“data”: “ON”}
