Helec LoRa 32 (V1)LoRaWAN Node

(Marcos Chiodi) #1

Hello, I’m starting to study IOT and I’m having a lot of difficulties on my first project, can anyone help me? I’ve been working on it for days. I do not know if the problem is in the gateway or in my source code.

#####a very valid information ######
“Data” appears every 60 seconds on my arduino serial monitor (reported below), but no packet information appears on my gateway !!Much less in TTN

The goal is to communicate LoRa 32(v1) node of LoRaWAN Heltec in The Things network

#I’m following this tutorial

#My Arduino IDE version 1.8.8

#My Board HELTEC ESP32 LORA(v1)+ Transceiver SX1276

#My gateway is configured like this:

GW_ID “CC50E30C8513”
GW_NTP_SERVER “br.pool.ntp.org
GW_ROUTER “router.us.thethings.network” <- ( I am from Brazil )
GW_PORT “1700”
GW_FREQ 915000000
GW_BW “BW250”
GW_LAT “-25.410966”
GW_LON “-49.223382”
GW_ALT 935
GW_PWD 878787

##Excerpt from my source code

Serial.println(F(“EV_TXCOMPLETE (includes waiting for RX windows)”));
if (LMIC.txrxFlags & TXRX_ACK)
Serial.println(F(“Received ack”));
if (LMIC.dataLen) {
Serial.println(F(“Received “));
Serial.println(F(” bytes of payload”));
// Schedule next transmissionos_setTimedCallback(&sendjob, os_getTime()+sec2osticks(TX_INTERVAL), do_send);
// data received in ping slot

##Excerpt from my source code

elif defined(CFG_us915) // defined in libraries
// NA-US channels 0-71 are configured automatically
// but only one group of 8 should (a subband) should be active
// TTN recommends the second sub band, 1 in a zero based count.

I’m grateful


please format your post
we don’t like big chunks of copy/pasted code.
after you’ve cleaned up I will move your post to the right topic

Do you have a single channel gateway? If so, you will receive just a fraction of the packets, so be patient.

Sorry I did not know!! I hope it is now acceptable.
Thank you very much


No it isn’t.

I don’t understand your question, you have to supply more information and start reading a bit on this forum.
If you have problems connecting your build node you must tell us what type of gateway you use and explain what your problems are and what you tried yourself.
Also show some screenshots from the console, from the node and your gateway.

I want to make my board ESP32 Lora (v1) communicate with the TTN.
But I can not even communicate with my gateway! Can you help communicate with the gateway first?


show TTN console screenshot from your connected gateway … not arduino IDE, and what gateway do you use ? I think some single channel dragino

(Marcos Chiodi) #8

I did not register my portal in ttn, I’ll do it now. But even without registering the gateway, the package would have to appear on it, right?
Yes, gateway single channel


ok… when it’s connected and you have searched this forum first (‘dragino’ ) start again :sunglasses:
