Re: BLE: limited number of services and characteristics

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 ...

Re: Automatic bootloader mode in ESP32_dev_kitc_v4

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.

Automatic bootloader mode in ESP32_dev_kitc_v4

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 ...

Re: Wifi BLE coexistence using Arduino IDE

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.

Re: Wifi BLE coexistence using Arduino IDE

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

Re: Wifi BLE coexistence using Arduino IDE

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 ...

Wifi BLE coexistence using Arduino IDE

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 ...
