Hello,
i have a short question. How can i convert one byte (0x0a) to an Integer (10)?
I transmit the lora tx power from the base to the receiver, that every unit have the same txpower.
I use this example: https://github.com/sandeepmistry/arduino-LoRa/blob/master/examples/LoRaDuplexCallback/LoRaDuplexCallback.ino
Thats my code in the base, where is the txpower value transmitted.
void sendMessage(String message) { LoRa.beginPacket(); LoRa.write(destination); LoRa.write(localAddress); LoRa.write(byte_txpower); LoRa.write(msgCount); LoRa.write(message.length()); LoRa.print(message); LoRa.endPacket(); msgCount++; }
Now when iam reading the transmitted data with byte incomingTxPower = LoRa.read(); // incoming txpower
byte incomingTxPower = LoRa.read(); // incoming txpower
And the value was a 17, I get only the 23.
I read in this forum, but i didnt understand it.

You need to read in this sequence to get txpower.
byte recvID= LoRa.read(); // incoming txpower byte sendID= LoRa.read(); // incoming txpower byte txpower = LoRa.read(); // incoming txpower
