Hi Chegewara, THANK YOU!!!!! :D It fixed the problem. Effectively I just removed the deinit and init; and added the esp_ble_gap_set_device_name and it works fine. Obviously between 2.0.0 and 2.0.4 something had changed. It now runs 2.0.4 nicely. Whilst doing this fix earlier, your code did not initi...

Hi Chegewara,

Were you able to reproduce this re-advertising issue?

Please test the relevant part of the code, or at least advise what are the two workarounds for this issue.

regards,
David

Hi Chegewara. How are you going with reproducing the advertising bug? There is another reason I want to get this issue sorted out. I am using the same re-advertising technique on a another program which used the ESP32-C3. That program talks to a 128 x 64 OLED and other I/O devices. I found with ESP3...

Hi. Thank you! If you do that, and you ever visit Melbourne (Australia), I will shout you lunch and free beer. It will be interesting to see how to get around this issue. It may also help others who might come across a similar issue.

Hi. I tried several things. I replaced esp_ble_gap_set_device_name(advertText); it did not fix the problem. Advertising did not restart. I also added a 20ms delay between each line of code in that advertising code - no difference. I don't think timing delays is the issue. However, you may have hit o...

Hi Chegewara. Line 59 to 65 at setup is repeated on lines 110 to 116 in the loop, but on line 108 we de-init the device. So isn't that effectively re-advertising? And it does not explain by 2.0.0 of the ESP32 board driver works fine and newer versions all fail with the same code. There will be one o...

Hi. I have a weird problem with BLE. If anyone can help, it would be greatly appreciated. The issues is ONLY found on any Arduino ESP32 board drivers newer than Version 2.0.0, but 2.0.0 works perfectly. So, the latest 2.0.4 shows the bug. Is there a coding workaround? My unique application sends a t...

No worries, that is good info. I sort of expected so, because really there is nothing related to the CPU variant, as at the lowest level is just I2C comms.

Thanks!

Hi. I want to use a 128 x 64 OLED with I2C, on an ESP32-C3 using Arduino. I ordered a few OLED displays, but they won't be here for a week or two, and I need to know fairly urgently. That is, will the standard SSD1306 driver work on the ESP32-C3 in the Arduino IDE? Has anyone done this, or at least ...

Gents, I have just spent the past 3 days (12 hour days) reading everything I could about BLE. Last Bluetooth project was a Bluegiga (now Silicon Labs) classic bluetooth device I did coding for about 7 years ago, so I was rusty. Today I built a BLE tester using a Raspberry Pi and GATTTOOLs under Linu...
