Arduino_LoRa_Generic_Sensor - ascii' codec can't decode byte 0xd7 ....

I understand that something is wrong with decoding, but what ?

What are you sending? Can you try by launching the gateway with

sudo ./lora_gateway

to get raw output?

Don't forget to kill all gateway related process (option K of cmd.sh) before launching the command in a terminal.

Hi,

Sorry for late response. I did like you said and this is the output:

I try to send temperature and Humidity from DHT22 which is connected to Arduino nano. This is the output from serial on nano:

You have a lot of strange characters, don't forget that ASCII format is requied, so don't write directly floating point data, you have to convert into ASCII first.

...and what should I do to convert into ASCII? Sorry for stupid questions, but I am (not so young ;-) ) beginner ....
