Hello, I am facing exactly same issue. I am using Arduino IDE to code ESP-32 module. Currently I am using BLE functionality to communicate with our mobile app. There seems to be limitation on number of BLE services which can be created. Even If I create more than 7 services, only 6 are visible. I fi...

Hello Everyone,

Just an update, after hours of debugging, I came across solution.
Added 10uf capacitor between EN and GND pin. Now I can upload firmware without pressing boot button.

I had similar issue.

Hello Everyone, I am new to ESP32 and recently purchased ESP32_dev_kitc_v4. I am using arduino IDE with esp32 core provided. Query: I need to press boot button everytime to start firmware upload. However, the adafruit huzzah feather esp32 module (https://www.adafruit.com/product/3405) doesn't have a...

advertisedDevice.getScan()->stop();

I tested this, I am unable to make POST call.
But when I use "btStop()" at the start of post call, it works. Problem is if I use btStart(), esp32 resets. If I don't use btStart() then esp32 is unable to receive data via BLE as its not advertised.

I tried btstop() and btstart(). It works properly, however ESP32 resets everytime btstart() method is called.

Thanks for the response :) You can also try to stop scan during wifi connection. Can I use the function mentioned below? btStop(); or advertisedDevice.getScan()->stop(); If you set it also to 0x100 then radio is 100% occupied by bluetooth and no time for wifi. Understood. I will try lesser values an...

Hello Everyone, I am new to Esp32 and currently using ESP32 NodeMCU-ESP32 with arduino IDE. Please forgive me if I have posted it in incorrect forum. I am working on application which requires co-existence of BLE and Wifi. Here's the data flow; ESP32 act as Master -> connects to BLE device which pro...
