WiFi LoRa 32 V3 Documentation repository

#1

In order to alleviate the lack of organized documentation availability on WiFi LoRa 32 V3, it could be a good idea to share the links related to this unit that we may consider worth sharing. I start the repository with some of the links that so far have been more useful to me. Please add the ones you may consider interesting for the Community.

I would like to recommend using RadioLib for LoRaWAN with the V3 boards - which includes the WiFi LoRa 32 V3.

—> Radiolib added !

#5

Meshtastic also support this board: https://meshtastic.org/docs/hardware/devices/heltec/?heltec=v23
also some pointers in platformio https://github.com/espressif/arduino-esp32/tree/master/variants/heltec_wifi_lora_32_V3 which allows to build 433 for misc interaction with domotic or 868 for Lora (using radiolib and rtl_433)

How to know the correct pins to use in SX1262 radio = new Module(??, ??, ??, ??) ?

#7

@tanguy-e the comment on the line above says what the names of the pins are - you can look at the pinout (likely one of the links in an earlier post)

#8

I found nothing about LoRa in “WiFi LoRa 32 V3 Pinout” but i found them in the schematic diagram.
so SX1262 radio = new Module(8, 14, 12, 13); should work ?

Hi @bns @jivaro
I am also doing some experiments on this same board Heltec Wifi Lora 32 (V3), and using the library available here https://github.com/HelTecAutomation/Heltec_ESP32 i am able to use class A and class C examples and some modifications on top of those examples. But i am still wondering is there any way to get the things done in Class C or is there any library available or previous work done by anyone or has anyone able to implement class B for this device.
Please i am seeking for help and any help will be a great benefit for me, or any direction how can i implement class B for the same device on end node side, basically my complete setup looks like using Heltec Wifi Lora 32 V3 as end node and waveshare sx1302 lorawan gateway hat on top of raspberry pi as Gateway and chirpstack as LoRaWAN-Servers.

Hoping for the response.

Thanks

Double posting isn’t useful. It means you could end up with two lots of answers, some duplicated, some conflicting and split the efforts of volunteers answering. Also, mild thread hijack!

I can put half the answer here and the other half in the other thread. I’ll go with every other letter:
