Sounds like a good approach Rop, Unfortunately I won't have time to test it since I've got a deadline for some of my own projects. I particularly like your suggestion of changing the name of the main heltec.h file to heltec_unofficial.h. Many thanks for your excellent work to clean up the Heltec "soup". |

I was able to test this. Seems to work. Thanks for the quick response. I had a lot of trouble with the Heltec libraries, but I like the hardware. Let me know if I can contribute at all. I tried a couple of your examples to make sure things compiled and uploaded. I still had to install HotButton and TimeLib, per another post here. Here some notes for windows users: ~/Library/Arduino15/ ----> c:\Users<user>\AppData\Local\Arduino15 |

HotButton is listed as a dependency, so that should come automatically when the library is installed using the library manager. Why TimeLib? |

After cleaning out all Arduino files, I started with a fresh install and followed your instructions above. Then I selected examples from File->Examples-Heltec_Esp32_Lora_v3. First one was Lora_rx_tx. That would not compile unless I manually installed HotButton. The second one was under display demos->clock demo. That was importing TimeLib.h, so I installed the Time library. I don't know how examples work and if they are supposed to prompt to install for dependencies or if a user has to figure that out on their own. Just mentioning it. |

Thanks for testing! The dependency (HotButton) probably did not get installed because you just got the library from GitHub (as per the test instructions) and not via the library manager. The clock example indeed uses the time library. Says in the source, I think, will check. That came with the display library, of which I do not need to carry a fork anymore since they took all my changes. Will make that a dependency soon. |

I can confirm that adding https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json was all it took to get it working on the latest Arduino IDE (2.3.2). Thanks for this :) |

I installed esp32 from Espressif as per the instructions above (point 2) but I don't have any folder /boards under ~/Documents/Arduino/libraries/Heltec_ESP32_LoRa_v3. P.S. Before getting to you I tried the Heltec libraries and boards without success (impossibile to compile any example). |

For some unknown reason I had version 0.5.0 of the library. Strange since I installed it just yesterday through Arduino IDE... |

P.S: I am not able to make the OLED display to work... tried the example SSD1306SimpleDemo: it compiles and uploads smoothly but the OLED remains off. Forced SDA and SCL to 19 and 18 and also to SDA_OLED and SCL_OLED but no change... |

Which of the three boards do you have? |

Also you say SSD1306SimpleDemo, which is the name as an example for the display library. I would use the version of the example from my library, where it's under File / Examples / Heltec ESP#2 LoRa v3 / display demos / SimpleDemo. |

Tried the sketch you suggested from your library (I dind't spot it before) but still nothing on the display. Compilation and upload ok (see below the report), but the display remained off. OLED display was working ok when the board (ESP32 WiFi LoRa v3) was brand new, then it stopped working when I uploaded different WiFi and Web Server examples (which is expected). _Sketch uses 355237 bytes (10%) of program storage space. Maximum is 3342336 bytes. Leaving... |

There was a bug in display demos/SimpleDemo, I fixed it by adding The other display demos work. Here at least. If DrawingDemo doesn't work for you, it's likely that you are having a hardware problem in addition to there being a bug in SimpleDemo. |

Sorry, I have what seems a problem of compatibility of your library with other libraries, in particular when I introduce a both.print in my sketch the serial monitor keeps on scrolling the following message: _Rebooting...

What kind of hardware do you have? Regular or Wireless Stick? |

It is a ESP32 WiFi LoRa V3 board. BTW I am using pin GPIO 4, 6, 3 and 5 for the SPI to the BME180 board, as far as I understand from the schematics the OLED uses GPIO 17, 18 and 21 so it should not be a conflict between the pin used by the two devices (that was my first hypothesis). |

Can you show the code where you set up the SPI for the BME180? |

It worked perfectly fine. Thank you! BTW: I see the OLED scrolls whenever a new line is added. How can I clear the display, so the position of the new line does not depend on the past scrolling history? |

Hi Ropg, sorry to bother you, but following STRICTLY your indication for the latest version of your precious library using an Heltec Wireless Stick V3, I get the runtime error : E (44) i2c: i2c_set_pin(882): scl and sda gpio numbers are the same |

I had the same issue yesterday after an update of some libraries. I suspect it is the OLED libraries from Adafruit (if I recall...). BTW is there a log or history of the library updates in Arduino IDE? I always accept all the updates proposed but in this case I may want to get back, but I am not sure which libraries was impacted but the yesterday update. |

Hi Ropg,
- Arduino IDE 2.3.2 reinstalled after environment cleanup (e.g. delete of library directory under Documents/Arduino/library etc.)
- Phisical Board Heltec Wireless Stick v3
- Board selected in Arduino : Heltec WiFi Lora32 (V3) / Wireless shell(v3)/...
put inside the source file:
#define HELTEC_WIRELESS_STICK
#include <heltec_unofficial.h>
I should have done everything according to your last explanation contained in the readme file at the link
https://github.com/ropg/heltec_esp32_lora_v3

I confirm that after a new update of the libraries as suggested at the Arduino IDE startup everything is working nominal including BME280 (SPI interface, not I2C since I didn't manage to have that working...) and OLED. From what I understand it is this library https://github.com/ThingPulse/esp8266-oled-ssd1306 which contains the fix in version 4.6.1 |

IGNORE EVERYTHING IN THIS THREAD
HERE FOR HISTORICAL REASONS ONLY...
EDIT: I changed board definitions again, reverting to using Heltec's own definition. Making my own is just too much of a maintenance nightmare: the Arduino ecosystem is not built for alternative board definitions and working around that is not worth it in this case. The README has been changed accordingly. There will be a separate HOWTO for using different partitioning of the flash for those that needed that feature from my own definitions.
Hi all,
I'm thinking of changing how the board definitions are added, because having my own board manager URL – while it seemed such a cool idea at the time – is a major can of worms. The intricacies of the Arduino Board Manager process would force me to stay up on way to much arcane stuff that I don't want to have to keep updating. I think I have a better way of doing this, that is less complex and hopefully not as shaky as the current method. Sadly a bit more involved on the user end, but can't win them all.
If you've been having trouble, please help me test this before I add it to the main README and remove the other method.
0. Clean up a bit
~/Library/Arduino15/. There, delete boards.json and from the packages subdir delete everything related to the heltec unofficial package1. Make sure you have the latest version of this library.
On the Mac this would be:
2. Install esp32 from Espressif
https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json3. Copy files
~/Library. Theboards-ht_u.txtneeds to be APPENDED to the existingboards.txtfile. If you're not on a Mac, change these directories to where your files live. (I will naturally make this more clear in the eventual instructions in the README.)4. Use
To anyone that's been having issues: please let me know if this works for you.
I'm also thinking of changing the name of the main heltec.h file to heltec_unofficial.h so the library can coexist with the heltec libraries made by Heltec.
