NimBLE is also part of the Apache MyNewt project. Documentation and answers to questions in the forum indicate that the ESP-IDF should support this enhancement of the v4. My ESP32 acts as a central role and initiates a connection to a peripheral. Is there any way to get the MAC and RSSI of I am trying to continuously scan around for BLE beacons using NimBLE stack on ESP32-pico on ESP-IDF 4. Only I had to do a little modification to your code. Using Add COMPONENT_DEPENDS += NimBLE to your application component. This function requires that: o No peers are connected, and o No GAP operations are active (advertise, discover, or connect). For more information on the improvements and additions please refer to the class documentation This function gets called automatically by the NimBLE host on startup; manual calls are only necessary for replacing the set of supported services with a new one. For any projects that only require BLE, NimBLE is simpler to use—it has a smaller code footprint and a simpler API to get your project going.

I tried going raw from the api but it's basically the same logic and still get the same problem. Hello All, I have perused through any documentation I can find with regard to the ESP-IDF support of DLE (Data Length Extension). 2 SDK. Using VC Code as an editor and menuconfig for idf. I did bond, I can read/write characteristic in Battery and HID service, subscribe notifications; after read characteristic when rx notify, ESP32 nimBLE: How to send notifications. flags = BLE_GATT_CHR_F_READ | Hi guys, i'm use a nimble server from version v4. h" #include "nvs_flash. The underlying controller is still the same (as in case of Bluedroid) providing I have written a tutorial about use of nimble BLE with esp32 (read, write , notify ) for easy understanding of everyone https://github.
