Same issue on ESP32-C3 and 2.0.9.

@sidwarkd do you have a temporary fix for this? I tried disable the memory release, however when I try to connect to it through rainmaker app, it always fails and no error in console.

can you please help with triage @PilnyTomas? Thanks

@MingyaoLiu Yes, the fix which worked for me was to simply comment out the call to esp_bt_controller_mem_release since, once you release that memory, it cannot be reclaimed per the docs. Here is a link to my fork with the change on line 261 of esp32-hal-misc.c. https://github.com/deploythefleet/arduino-esp32/blob/master/cores/esp32/esp32-hal-misc.c#L261. No other changes were required to get the sample working.

Using the provided sketch, I was not able to reproduce the mentioned Error.
Using ESP32, latest arduino-esp32 master branch 2.0.11
Could you please retest on current version?

Closing this issue as expired, if needed you can reopen.

@PilnyTomas I am not able to use the master branch as it requires v5.1 of the IDF. When I check out the 2.0.11 tag I know longer get the error but I also do not get any WiFi networks returned in the provisioning app. If I roll back to my fixed branch I see them appear again. Then I tried different tags:

2.0.11 - No error but no WiFi networks returned in the app
2.0.12 - Back to getting the error again
2.0.13 - Same error
2.0.14 - Same error

So at least on the 2.x release it seems like this was kind of fixed and then regressed again. Is there some other commit I should try?

Researching this more and definitely a regression. The following shows 2.0.9 on the left, 2.0.10 in the middle and then 2.0.12 on the right which essentially puts it back to the way it was. So definitely broken again in 2.x. Will this be fixed in 2.x?

@SuGlider PTAL.

@sidwarkd / @me-no-dev - I have made it work using the sketch presented in this issue.
Important details:

• Upload the Sketch using the Erase All Flash Before Sketch Upload: "Enabled" in order to erase previous WiFi/BLE sertup.
• In the ESP BLE Prov APP don't forget to change the Prefix to the one the sketch is using with Lower Case Prov_

These are the step that I used to make it work:
1- Downloaded the ESP BLE Prov APP in my Android phone.
2- Uploaded the sketch to the ESP32 - USING the option Erase All Flash Before Sketch Upload: "Enabled"
3- Turn the Android phone Bluetooth ON and open the ESP BLE Prov APP.
4- Click on the "Provision New Device" button
5- Ignore the QR Scan and click on "I don't have a QR code" button. Change the Prefix to lower case "Prov_"
6- Android will scan BLE device. It shall list "Prov_123" in the Devices List. If necesary click on "Scan Again"
7- Click the device "Prov_123"
8- Confirm the proof of possession PIN for Prov_123 as "abcd1234" and click the "Next ->" button
9- Click on "Join Other Network" and enter your SSID/Password for your local WiFi network. Attention to Lower/Upper case.
10- Press the "PROVISION" button and wait for the process to complete.

This is the output:

I have used Arduino Core 3.0.0-alpha2 ...

@sidwarkd

2.0.11 - No error but no WiFi networks returned in the app

I also get no list of WiFi networks in the APP, but I can set it manually with "Join Other Network" button.

@SuGlider On older versions the scan actually returns a list of WiFi networks but the later versions do not. I was able to "Join Other Network" but the flow is supposed to return a list of available WiFi networks. That is a bug, right?

The quesiton would be if this is an APP issue or ESP32 Software issue. Both could supply the list of WiFi SSIDs, given that both shall be close to each other for a BLE connection.

@sidwarkd - I have just run all over again here with Arduino Core 3.0.0-Alpha2 and it is running perfectly fine, including listing the WiFi SSIDs in my Android APP.

Sometime it doesn't list it immediately, but it seems to be running fine with no bugs.

@sidwarkd - Please try it again from scratch. It shall run fine.

@azmi-plavaga can you please retest on version 3.1.0-RC1?

@lucasssvaz can you please retest this on RC2? Thanks a lot

@VojtechBartoska The sketches from this issue and the examples both with ESP32 and ESP32-C3. Everything worked as expected.

I am having the exact same problem. It was working fine on Arduino IDE. I migrated the project to PlatformIO. After migration, WiFi BLE Provisioning stopped working. Please see the log below:

E (10920) simple_ble: simple_ble_start enable controller failed 259
E (10921) protocomm_ble: simple_ble_start failed w/ error code 0x103

Thanks

Edit:
As mentioned above, I made it work by commenting the line below:

esp_bt_controller_mem_release(ESP_BT_MODE_BTDM);

FYI

@Jason2866 Have you ever seen this issue ?

Without an example sketch and the used platformio.ini can't say anything.
Can't imagine there is an issue, since Arduino code is same as when using ArduinoIDE.

Closing this. Seems to be a migration issue or something else, using old release.

If tested against current/updated software and problem persists, open new issue.

Facing same issue (runtime error) when using PlatformIO IDE (platform: pioarduino | core: v3.1.3) and ESP32 (nodemcu-32s) board.
The same code works as expected when using Arduino IDE (core: v3.1.3).

@Jason2866 Sorry to disturb, can you please take a look at this?

Hey @kumardeo ,

I had the same problem when I was working with ESP32.

I added this to my platformio.ini and it worked.

build_flags = 
	-D SOC_WIFI_SUPPORTED=1
	-D BLUEDROID_ENABLED=1
	-D CONFIG_BT_ENABLED=1
	-D CONFIG_BT_BLE_ENABLED=1

Hope it helps!

Didn't work for me :(

Issue can be reproduced with this example https://github.com/pioarduino/test-rainmaker/tree/wifiprov

Fix as suggested here is working #8176 (comment) to solve the issue
