Encoding message sent to TTN

[Johan_Scheepers]

There are a few extent post on working with bytes and how you should send your data over LoRaWAN.

If you encode your data to hex and decode, you save a lot on air time and battery life.

If you search the forum lots of recourses.

Decrypting messages for dummies

Thank you a lot, you have really clarified some basic facts. For this purpose is LoraEncoder function - for example to change measured value to number representation of this value, isn’t it? To be sure that this is the right way: way from measured Temp=23.45 to 0x09 0x29 on the TTN Application data page with as small payload as it possible is (from Arduino): float Temp = 23.45; LoraEncoder encoder(buffer); encoder.writeTemperature(Temp); LMIC_setTxData2(1, buffer, strlen((char *)buffer), 0)…
