May be this is a trivial question, but I will appreciate anyone’s help. I am using the code Helium Heltec LongFi example in a Heltec Esp32 LoRa V2 to connect the Helium network.
If a use the Heltec example code “as is” and works fine!
If I increase the appDataSize from 4 to 12 I can only uplink to Helium network the first message with 12 bytes, but next messages are 0 bytes.
I would like to allow to transmit 4 float numbers but I don’t know the correct parameter to change.
