Connect Pycom FiPy device Senet LoraWAN OTAA

Although Pycom states they utilize The Things Network, I could not ‘join’ my FiPy device. I suspect no coverage near me. However, I also have been trying senet using its appEUI and appKEY. Still will not connect. My device is registered at (my device appears on the dashboard) and am using below example code. Please help.

from network import LoRa
import socket
import time
import ubinascii

Initialise LoRa in LORAWAN mode.

United States = LoRa.US915

lora = LoRa(mode=LoRa.LORAWAN, region=LoRa.US915)

create an OTAA authentication parameters

app_eui = ubinascii.unhexlify(‘00250C000XXXXXX’)
app_key = ubinascii.unhexlify(‘9014A658F6B2CB462745D66CXXXXXXXX’)

initialize LoRa

lora.init(mode=LoRa.LORAWAN, adr=True, public=True)

join a network using OTAA (Over the Air Activation)

lora.join(activation=LoRa.OTAA, auth=(app_eui, app_key), dr=0, timeout=0)

wait until the module has joined the network

while not lora.has_joined():
print(‘Not yet joined…’)

print('Joined LoRaWAN, ',lora.has_joined())

create a LoRa socket

s = socket.socket(socket.AF_LORA, socket.SOCK_RAW)

set the LoRaWAN data rate

s.setsockopt(socket.SOL_LORA, socket.SO_DR, 3)

make the socket blocking

(waits for the data to be sent and for the 2 receive windows to expire)

s.setblocking(True) # for OTAA
#s.setblocking(False) # for ABP

send some data

print(‘Sending data’)
s.send(bytes([0x01, 0x02, 0x03]))

make the socket non-blocking

(because if there’s no data received it will block forever…)

s.setblocking(False) # for OTAA

get any data received (if any…)

data = s.recv(64)

Hi quantal,

Your device seems to be configured properly. Most likely there is no coverage where you are testing. We normally suggest that developers obtain a developer gateway from Multitech that will assist in sending packets to the network server. That way you can remove any coverage issues in your testing



Thanks. I will try that.
