Unable to built Arduino BLE Examples

[nkolban]

Howdy Raj,
Those error messages would be consistent with trying to build the app with a "board" other than an ESP32 board selected. Can you look in the Arduino IDE Tools menu and report back on the current setting for "Board"?

Your thinking on building the BLE ZIP file is sound. What I'll do is create an issue for creating regular "snapshots" of the ZIP file that will be available for "download and go".

Hi Neil,

I am using the board ESP32 Dev Module. I will try again to uninstall and reinstall Arduino. I shall get back.

It is really great that you will try to provide a downlodable library link in coming days. It is going to very helpful for me and others.

Many thanks,
Raj

Hi Neil,

Still no luck. I get the same built errors. I had reinstalled the arduino IDE and updated the ESP32 repository.

I attach the snapshot of Dev. Broad selected in Arduino as well the built error.

Out of curiosity since I see the error points to esp_log.h, I tried #include "esp_log.h to example code and also add esp_log_level_set("*", ESP_LOG_VERBOSE); in setup(). I also tried to change CONFIG_LOG_DEFAULT_LEVEL=1 to 5 in sdkconfig to see if that will help. Still the result was the same compile error.

Am I missing something? Do you think I try something different?

Many thanks,
Raj

Howdy Raj,
Just in case there is something not right in the ESP32_BLE.zip file, I have uploaded the version I am using. This can now be found here:

https://github.com/nkolban/esp32-snippets/tree/master/cpp_utils/Arduino

We also have some notes on installing a new version found in this doc:

https://github.com/nkolban/esp32-snippets/blob/master/cpp_utils/ArduinoBLE.md

Let's try using the ZIP file from this location.

Thanks for your Arduino.ESP32.Dev.Board.pdf file. That shows exactly what I was looking for and that looks fine.

Can I also assume that if you try and compile and flash other ESP32 applications from your Arduino IDE that they compile and run cleanly?

Hi Neil,

So many thanks, I will try out the library you provided and get back to you. Yes, that is right I am able to compile and run other ESP applications on my Arduino IDE.

Many thanks,
Raj

If you need some live support later today we can arrange something if you desire. I am in US central time. Skype will be the best way to reach me at "neil.kolban". My availability is about 20% today ... apologies for that.

[rrajkum]

Hi Neil,

That is very kind you offer to help with live support. I am based in Denmark. I am just about the try the new library. I would not like to distrub your weekend. Please allow to grab your help if I continue to face issues. Let me get back.

Many thanks,
Raj

Hi Neil,

I tried with new library. The same issue persists. May be I need to grab your offer to help via Skype. I feel uncomfortable to trouble you today. How about tomorrow 11 Sept any time slot that suits you between 09:00 - 13:00 your time? It is a time difference of minus 7 hrs between US central and Denmark.

I hope to catch-up on Skype.

Many thanks for all your support,
Raj

I had a similar issue. I'm using Neil's library via PlatformIO and not the Arduino IDE, so this may or may not help you. In my case I was linking against an old version of the ESP SDK (I think 0.9?) which didn't have some of those Bluetooth constants defined.

Howdy @ADeeds
I had the opportunity to chat with mr @rrajkum this evening and that was exactly the issue (so far). The problem was that the ESP32 Arduino package installed into the Arduino IDE was indeed back level (just as you thought). Mr rrajkum is going to download the latest from Github, re-install and re-test.

[rrajkum]

Many thanks Neil, with your support things are working good after downloading the latest repo from Github.

There seems to be link issue with ESP32_BLE_Arduino-master.zip. We can close this issue and track separate.

Now I confirm that examples compiles, links and executes good!
