Would greatly appreciate any help for an issue that I thought I could solve with online searches. Unfortunately, despite finding a lot of references to similar error messages, I have not resolved my issue here.

I have -2- of the Uputronics LoRa Expansion Boards on a couple of Raspberry Pi SBCs. Wanting to learn how to interface with them, and not being a programmer, this repository looked like it might be something I could handle since I've used Python in the past for various projects.

Pi #1 (Pi version 2) is setup as my receive test unit and Pi #2 (Pi 3b+) is doing the transmitting. Their python versions are as follows:

pi@k4kdr-lora-1:~/pyUputronics $ python --version
Python 2.7.9
pi@k4kdr-lora-1:~/pyUputronics $ python3 --version
Python 3.4.2

pi@k4kdr-lora-2:~/pyUputronics $ python --version
Python 2.7.13
pi@k4kdr-lora-2:~/pyUputronics $ python3 --version
Python 3.5.3

I run the receiver (Pi #1) with the following command:

pi@k4kdr-lora-1:~/pyUputronics $ ./rx_cont.py --sf 6 --freq 434.475 --bw BW20_8

... and Pi #2 is setup to transmit with the following command:

pi@k4kdr-lora-2:~/pyUputronics $ ./tx_beacon.py --sf 6 --freq 434.475 --bw BW20_8 --single

... and appears to work correctly on the TX side:

pi@k4kdr-lora-2:~/pyUputronics $ ./tx_beacon.py --sf 6 --freq 434.475 --bw BW20_8 --single

Press enter to start...
Mode <- STDBY
Mode <- TX
Mode <- STDBY
tx #1

... however, when Pi #1 receives the transmission, I get:

pi@k4kdr-lora-1:~/pyUputronics $ ./rx_cont.py --sf 6 --freq 434.475 --bw BW20_8

// cut //

Press enter to start...

    print(bytes(payload).decode())
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xbc in position 5: invalid start byte

... there are a LOT of references online to this 'utf-8' error but I've not been able to get any of the suggested solutions to alter my results here.

FYI, both devices give the following:

pi@k4kdr-lora-1:~/pyUputronics $ echo $LANG
en_GB.UTF-8

Thanks in advance for any pointers particular to how I might get around this!

Great work here and easy to follow!

How hard would it be to set up something similar to https://github.com/sourceclimber/LoRa_TTN_Raspberry with this Uputronics card?

I have run the setup according to your instructions however am missing lora_util.py program.
Further the commands : from hoperf.LoRa import *
from hoperf.board_config import BOARD
fail to be recognised in python 3. Can you please amend this issue so it is possible to A) obtain and run lora_util.py and also allow the hoperf.LoRa board to run.
