ESP-IDF BLE throughput GATT SERVER demo
|
|
========================
|
|
|
|
This is the demo used to test the BLE throughput, this demo should used with throughput client demo together.
|
|
The throughput of BLE can up to 720-767 bits/s between to ESP32 board.
|
|
Note:
|
|
1. In order to maximize throughput, we need to set the uart print baud rate at 921600 or more (make menuconfig --> Component config --> ESP32-specific --> UART console baud rate --> 921600(or 1500000));
|
|
2. We can only test notify or write throughput at the same time, this demo default to test the notify throughput, if want to test the write throughput,
|
|
please set: make menuconfig --> Component config --> Example 'GATT SERVER THROUGHPUT' Config ---> then select the 'test the gattc write throughput' option
|
|
3. This demo only test unidirectional throughput, if you want to test the bidirectional throughput please change the demo by yourself.
|
|
4. Should change the CPU frequency to 240MHz in the make menuconfig --> Component config ---> ESP32-specific ---> CPU frequency (240 MHz)
|
|
5. Should change the bluetooth controller and Bluedroid run in different Core in the make menuconfig --> Component config ---> Bluetooth ---> The cpu core which bluetooth controller run (Core 0 (PRO CPU)) & Bluedroid Enable ---> The cpu core which Bluedroid run (Core 1 (APP CPU))
