Is there any example program which uses BLE features with out using external MCU and tx/rx some data using UART.

May i know if any one tested the BLE-range(distance) of ESP32-worver-ie as server and with out connecting the external antenna

by using advertisement data we can update name, its enough for connection. 2) 0x02, 0x01, 0x06, tells about flags in 0x06 - Bit 0 :Indicates LE Limited Discoverable mode Bit 1:Indicates LE General Discoverable mode Bit 2:Indicates whether BR/EDR is not supported . Bit 3:Indicates whether LE and BR/E...

follow above link and see generic access profile for advertisement types.
Advertisement data helps the client to know about the device link name, services, flags...

static uint8_t ext_adv_raw_data[] = { 0x02, 0x01, 0x06, 0x02, 0x0a, 0xeb, 0x03, 0x03, 0xab, 0xcd, 0x11, 0X09, 'E', 'S', 'P', '_', 'B', 'L', 'E', '5', '0', '_', 'S', 'E', 'R', 'V', 'E', 'R', }; you can find the advertisement raw data like above, in that array based on your required name change the le...

Try to change name in BLE advertisement data, you will see name change in light blue application after connection.

Thanks for your replay ,

I am using esp32-Wrover-IE for developing, downloaded provided BIN files and connected UART1 to external MCU for BLE application.
now my question is, is there any way to use MODULE itself for BLE application(Server) without external MCU
