Cannot create new project LORA 32 (V3)

PlatformIO IDE
1

Hi
I’m trying to create new project for LORA32 V3 board.
I receive this error:

PIO Core Call Error: "Resolving heltec_wifi_lora_32_V3 dependencies…\r\n\n\nUnknownBoard: Unknown board ID ‘heltec_wifi_lora_32_V3’

How to resolve?

Thanks

What is the content of your platformio.ini?

3

None because platform not create project at all

4

Looks like something is broken.

  1. Close VS Code
  2. Delete the directory
    • Windows: C:\User\<username>\.platformio
    • Linux: ~/.platformio
    • Mac: /Users/<username>/.platformio
  3. Restart VS Code and wait until PlatformIO finished reinstalling
  4. Try again
5

Done, now hold on project wizard and no folder is created

6

I have halted pressing on cancel and project is there!
Please create yourself this kind of project for test…

7

Create the project manually:

Create a project folder. Inside that folder
create a platformio.ini:

[env:heltec_wifi_lora_32_V3]
platform = espressif32 @ 6.12.0
framework = arduino
board = heltec_wifi_lora_32_V3

Crate a subfolder src.
In that folder, create a main.cpp:

#include <Arduino>

void setup() {
}

void loop() {
}

cd into the project folder and start vs code by running the command: code .

ok but test if you can create it by wizard. Other could have problem.
I have found this gityhub page. Seem that there are some problems with this board
ropg/heltec_esp32_lora_v3: Proper working Arduino library for the Heltec ESP32 LoRa v3 board, as well as for Wireless Stick v3 and Wireless Stick Lite v3. Uses RadioLib

9

How is that related to PlatformIO ?

10

I don’t know.
If also you creating this kind of project encounter my same problem maybe this page could help. It is only a suggestion

11

It does not help because it is not related.

Did creating the project manually work for you?

12

no, while wizard was freeze I click on cancel and project appeared correctly.
Now I’m using that library but not see nothing on oled screen…

13

Does a “Hello World” or “Blink” sketch work?

14

none example work for now

This configuration work:

[env:heltec_wifi_lora_32_V3]
platform = espressif32
board = heltec_wifi_lora_32_V3
framework = arduino
lib_deps =
thingpulse/ESP8266 and ESP32 OLED driver for SSD1306 displays@^4.6.1
cwru-greener-pastures/Heltec_LoRa_OLED_Examples@^0.8.1

You must create image.h e copy in it content of image code

//Esempio di utilizzo OLED

#include <Wire.h> // Only needed for Arduino 1.6.5 and earlier
#include “SSD1306Wire.h” // legacy: #include “SSD1306.h”

#include “images.h”

Hi

I have found the problem:

Heltec starting from V3 of HTIT-WB32LAF create a sort of fork that disable people to use Espressif Board.

Check here:
Heltec ESP32 Series Quick Start — esp32 latest documentation

Please try to correct this problem

Thanks

Please file an issue to the developers at github. This is the communtiy forum. The users here are not involved in the development of PlatformIO.

Thanks

PS: It looks like the minimum requirement is Espressif Arduino Framework 3.x. PlatformIO supports Espressif Arduino Framework 2.x. So pioarduino’s Espressif32 Platform may be a solution for you.
