Heltec wireless stick lite v3 auto select problem

[vladosam]

Hi, I have problem with auto selecting mcu with my heltec board. I'm using starter lorawan example and on compile i'm getting "Unknown board - no automagic pinmap available". On 6.4.2 radiolib version I have this for my board "SX1262 radio = new Module(8, 14, 12, 13);" and if I add that to config.h it compiles. But in config.h there is section for Heltec wireless stick lite v3 board and it has other pinmap

#elif defined (ARDUINO_HELTEC_WIRELESS_STICK_LITE_V3)
  #pragma message ("Using Heltec Wireless Stick Lite v3")
  SX1262 radio = new Module(34, 14, 12, 13);

How can I use auto selecting mcu for this board, do I need to set something in Arduino IDE or in my code? Thanks.

The lazy option for now is to add this line in config.h for now:

#define ARDUINO_HELTEC_WIRELESS_STICK_LITE_V3

There are some problems with the auto-select which are being resolved through #1106. In the next update of RadioLib (although that will probably take a while) this is likely going to be integrated instead of whatever is currently happening in config.h. So for the time being, I'd recommend not bothering too much and adding the define yourself.

To be clear: if you select the Wireless Stick Lite V3 as per the Heltec-esp32 package, it should work I think. But if it doesn't, meh, not worth the time probably, it's so much easier to add the definition yourself.

Thanks, adding #define ARDUINO_HELTEC_WIRELESS_STICK_LITE_V3 sets board, but after upload I'm getting

Setup ... 
Initialise the radio
Initialise radio failed - ERR_CHIP_NOT_FOUND (-2)

I guess that is because pinmap for HWSLV3 on config.h is

  SX1262 radio = new Module(34, 14, 12, 13);

and on my old code for radiolib 6.4.2 pinmap and spi setting is

#include <SPI.h>
SPIClass spi(SPI);
SPISettings spiSettings(2000000, MSBFIRST, SPI_MODE0);
// SX1262 has the following pin order:
// Module(NSS/CS, DIO1, RESET, BUSY)
SX1262 radio = new Module(8, 14, 12, 13, spi, spiSettings);

Are there other Heltec Wireless Stick Lite V3 board different pinmaps out there?

May i suggest to always use Arduino-ESP32 instead of anything from HelTec. There is a reason @ropg made an unofficial HelTec LoRa32 V3 library.

Is it possible to add a note in the code base as general advice?

[StevenCellist]

It may be possible, but with the upcoming RadioBoards it will work just fine. So there should be no need for it and is subsequently outside the scope of RadioLib, I'd say. Wish I could pin it as a message on the Heltec forum...

I want to use Arduino-ESP32 but radio initialisation failed until I changed board to Heltec Wireless Stick Lite V3. Also changed pinmap to

  SX1262 radio = new Module(8, 14, 12, 13);

On 6.4.2 I could use ESP32S3-DEV board in Arduino-IDE.
