Error while connecting - The requested operation is not possible

[ioTor]

Hi,

I have a Pysense board and a loPy4 with pyCom version: 1.18.1.r7

I trying to connect to "The Things Network". and keep getting the error:
File "<stdin>", line 28, in <module>
OSError: the requested operation is not possible

The line is:
lora.join(activation=LoRa.OTAA, auth=(app_eui, app_key), timeout=0)

What does that error message mean?. The Firmware is the current version.

Thanks for help!

@iotor Would you also show us the code related to Lora that was executed before that line.

Of course,:

import socket
import time
import ubinascii
import pycom
import network

from network import LoRa
from CayenneLPP import CayenneLPP
from pysense import Pysense
from LIS2HH12 import LIS2HH12
from SI7006A20 import SI7006A20
from LTR329ALS01 import LTR329ALS01
from MPL3115A2 import MPL3115A2, ALTITUDE, PRESSURE

pycom.heartbeat(True)

# Initialize LoRa in LORAWAN mode.
app_eui = ubinascii.unhexlify('70...')
app_key = ubinascii.unhexlify('11B0282A189B75..')

lora = LoRa(mode=LoRa.LORA, rx_iq=True, region=LoRa.EU868)
print("DevEUI: %s" % (ubinascii.hexlify(lora.mac()).decode('ascii')))
print("AppEUI: %s" % (ubinascii.hexlify(app_eui)))
print("AppKey: %s" % (ubinascii.hexlify(app_key)))

# join a network using OTAA (Over the Air Activation)
lora.join(activation=LoRa.OTAA, auth=(app_eui, app_key), timeout=0)

@iotor said in Error while connecting - The requested operation is not possible:

lora = LoRa(mode=LoRa.LORA, rx_iq=True, region=LoRa.EU868)

This line should be as below, if you want to connect to a Lora network like TTN or Loriot:
lora = LoRa(mode=LoRa.LORAWAN, rx_iq=True, region=LoRa.EU868)
