sensor dat to TTN

[Moalidinar]

Hi All I am doing my Hon's Project on IoT and LoRa network, I am trying to send my data over LoRa using VS(pymark) I have found some code here helped me but the problem is now the code I am using now below has an error when I try to run it it stops in line52, I am trying to send the reading from the sensors to TTN so with sorting the reading by the name of the sensor type or colours I am not sure how to get that the code below managed to work it out but still not working any help, please?

Describe the question

import time import pycom import machine from network import LoRa import socket import ubinascii

from LIS2HH12 import LIS2HH12 from SI7006A20 import SI7006A20 from LTR329ALS01 import LTR329ALS01 from MPL3115A2 import MPL3115A2,ALTITUDE,PRESSURE from pycoproc import Pycoproc pycom.heartbeat(False) pycom.rgbled(0x0A0A08) # white

Initialise LoRa in LORAWAN mode.

Please pick the region that matches where you are using the device:

Asia = LoRa.AS923

Australia = LoRa.AU915

Europe = LoRa.EU868

United States = LoRa.US915

lora = LoRa(mode=LoRa.LORAWAN, region=LoRa.EU868)

create an OTAA authentication parameters, change them to the provided credentials

app_eui = ubinascii.unhexlify('0000000000000000') app_key = ubinascii.unhexlify('5FD4AB619D3D90D3B8B2927A0117700B')

uncomment to use LoRaWAN application provided dev_eui

dev_eui = ubinascii.unhexlify('70B3D54990FF3C32')

Uncomment for US915 / AU915 & Pygate

for i in range(0,8):

lora.remove_channel(i)

for i in range(16,65):

lora.remove_channel(i)

for i in range(66,72):

lora.remove_channel(i)

join a network using OTAA (Over the Air Activation)

uncomment below to use LoRaWAN application provided dev_eui

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

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

wait until the module has joined the network

while not lora.has_joined(): time.sleep(2.5) print('Not yet joined...')

print('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, 5)

make the socket blocking

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

s.setblocking(True)

pybytes strings

pybytes_enabled = False if 'pybytes' in globals(): if(pybytes.isconnected()): print('Pybytes is connected, sending signals to Pybytes') pybytes_enabled = True

py = Pycoproc()

alt = MPL3115A2(py,mode=ALTITUDE) # Returns height in meters. Mode may also be set to PRESSURE, returning a value in Pascals print("MPL3115A2 temperature: " + str(alt.temperature())) print("Altitude: " + str(alt.altitude())) pres = MPL3115A2(py,mode=PRESSURE) # Returns pressure in Pa. Mode may also be set to ALTITUDE, returning a value in meters print("Pressure: " + str(pres.pressure()))

send to pybytes

dht = SI7006A20(py) print ('Temperature type',type(dht.temperature())) print("Temperature: " + str(dht.temperature())+ " deg C and Relative Humidity: " + str(dht.humidity()) + " %RH") print("Dew point: "+ str(dht.dew_point()) + " deg C")

change to your ambient temperature

t_ambient = 24.4 print("Humidity Ambient for " + str(t_ambient) + " deg C is " + str(dht.humid_ambient(t_ambient)) + "%RH")

li = LTR329ALS01(py) light = li.light() print ('light type',type(li.light())) print("Light (channel Blue lux, channel Red lux): " + str(light[0]) + ' ' +str(light[1])) pybytes.send_signal(0, light[0]) # channel Blue pybytes.send_signal(1, light[1]) # channel Red

acc = LIS2HH12(py) print ('acceleration type',type(acc.acceleration())) print("Acceleration: " + str(acc.acceleration())) print("Roll: " + str(acc.roll())) print("Pitch: " + str(acc.pitch()))

print("Battery voltage: " + str(py.read_battery_voltage()))

make the socket non-blocking

(because if there's no data received it will block forever...)

s.setblocking(False)

get any data received (if any...)

data = s.recv(64) print(data)

while(True): lit = li.light() acce = acc.acceleration() s.send(bytes([int(dht.temperature())])) s.send(bytes([int(lit[0])])) s.send(bytes([int(lit[1])])) s.send(bytes([int(acce[0])]))

s.send(bytes([int(acce[1])]))

#s.send(bytes([int(acce[2])]))
print("Sent data to and TTN")    
time.sleep(15)

I don't see anywhere in the code fragments where you're using our IoT SDK. We don't really have the ability to assist with issues outside that domain.
