the purpose is to pass data through bluetooth and pass it to uart2 transparently, your code is very similar to mine, the whole trick is in the functions esp_spp_cb () and esp_bt_gap_cb ( ) in the events that they handle, and find the data in the esp_spp_cb_param_t * param s...
Esp32 Ram|Unleash your IoT projects with the ESP32 LOLIN32 board, featuring MicroPython support and dual-mode Bluetooth for seamless connectivity..
The objective of this esp32 tutorial is to explain how to get started with the BluetoothSerial ESP32 library, in order to send data to a emulated Serial connection, operating over Bluetooth classic. The tests of this ESP32 tutorial were performed using a DFRobot’sESP-WROOM-32device integrate...

ESP32 to ESP32 Serial Communication Let us see an example of serial communication where the ESP32 master will send either ‘1’ or ‘0’ to the ESP32 slave. The slave will then receive that data and control an LED connected with its digital pin. We will use UART2 to communicate between...
Then you can enter the data to send over the BLE to ESP32, or it will be displaying the data received from the esp32. This connection is a UART (universally asynchronous receiver-transmitter). Which means it has both capabilities to send and receive data at the same time. In the first...
LCD interface: The development board has a 1.28-inch screen with 4-wire SPI communication on board, the SPI rate can be increased to 80MHz, and the touch uses I2C communication (the development board uses GPIO2 to control the brightness of the backlight, and two MOS tube control switch co...
The transmission timing from the ESP32 to the mobile phone is 48 bytes every 20MSEC - this is a real time project - I must keep this communication speed accurate. I need someone to help me with the BLE code / function that will be easy for me to add this functionality to my project...
