I need some help regarding BLE communication between ESP32 and Android / IOS . (2 ways communication). I have existing project that works great with Android mobile phone by using OTG USB cable. I want to do the communication with BLE instead USB cable. ...
I try to send 60kByte of data over BLE between two ESP32. As a start, I used the blecent example from NimBLE/ESP-IDF and so far the communication works great and reliable, but the speed is extremly slow. It seems, that I can only send exactly every 100ms a packet and I really ...

In thesetup(), it starts the serial communication at a baud rate of 115200. Serial.begin(115200); Then, you create a BLE device called “MyESP32”. You can change this name to whatever you like. // Create the BLE DeviceBLEDevice::init("MyESP32"); ...
In this tutorial, we will take an example of point-to-point communication between two ESP32 boards. Important Terms in BLE Here are some important terms which one should know while working with ESP32 BLE applications: GATT:GATT or Generic attributes which defines a hierarchical structure for dat...

This chapter focuses on Bluetooth Low Energy (BLE), a wireless communication widely used between two devices in close proximity to each other. Products choose to use BLE instead of Wi-Fi if minimizing energy use is particularly important and when direct communication with another device, such as...
Communication between the broadcaster and the observer(s) is unidirectional. The broadcaster is incapable of receiving data from the observers and is unaware of how many observer devices there are. GATT (Generic ATTribute Profile) The Generic Attribute Profile, or GATT, determines the format of the...
