Re: Error compiling the "hello world" example

The logs shows you didnt follow all steps. You did not git clone with --recursive flag.

Now you have to go to esp-idf folder and use command:

Code: Select all

git submodule update --init --recursive

Re: BLE: limited number of services and characteristics

I tried this code with esp-idf in PIO and i found this, which is very strange: BT_GATT: GATTS_ReserveHandles: no free handle blocks You can try to use this function and decrease numHandles: https://github.com/nkolban/esp32-snippets/blob/master/cpp_utils/BLEServer.h#L67 Each characteristic needs 2 ha...

Re: Will BLE provisioning with the NimBLE stack be supported in ESP-IDF 3.3?

I would like to add my 5 cents. v3.3 is LTS version and NimBLE is already added to v3.3, from users/programmers point of view v3.3 cant be fully considered LTS. Yes, i understand fact that v3.3 is a finished version and LTS in this case mean only critical code and bugfixes will be implemented, but l...

Re: CMake - Nested component

For sure you can use nested components, but it is easier to use PRIV_REQUIRES.
If you still want to use nested components then try to study
https://github.com/espressif/esp-adf
where esp-idf is used as component and all its components can be considered as nested components.

Re: OTA

You can use the same code with arduino, to use rollback you probably will need to use arduino as component, because IIRC it is not enabled in arduino, so you need to enable it in sdkconfig. Recently i am working on demo for m5stack to flash prebuild examples over BLE and i am using plain C code in p...
