According to my undrestanding from my studying about bluetooth BLE, here ESP32 acts as server and cellphone is the client. My question is that to reach this goal which one of the available examles in esp_idf is more suitable to use? Since I see both examples named "ble_spp_server" ...
I'm not sure if this is possible on esp32, but Broadcom Bluetooth chips has this really neat feature of controlling the power of another Bluetooth device(if it supported the lmp's power commands) Nintendo has used lmp_incr_power_req to turn on their devices and lmp_decr_power_req to tu...
All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here will be responsible for read(1)/ write(0) operation. If you plan to use the Registers instead of using the library functions, you need to give ...
Currently, I want to terminate the connection between esp32 and mobile application by pressing a button. How can I do that? I have checked and then found this function: Code: [Select all] [Expand/Collapse] esp_ble_gatts_close(gatts_if, conn_id); GeSHi © Codebox Plus Extension But...
Step 1: Open the scanner and connect to your Bluetooth device Step 2: After connecting to your ESP32, you can check the characteristic, and it will be displaying your text written. ESP32 as a Client As the name implies, second esp32 will be acting as a client and access the data from...
