Re: Equivalent of preferences in ESP-IDF?

Howdy, If by preferences you mean the ability to set configuration options at compiled time that can be customized ... then it might be that you can leverage the ESP-IDF build system. This allows you to add any number of custom options that can be modified via the "make menuconfig" tooling...

Re: [Video]: Bluetooth BLE and C++ classes

Howdy Sir, I think this may be related to this issue: https://github.com/espressif/esp-idf/issues/857 I also have seen strange symptoms with the latest BLE code is the pre-GA 3.0 BLE support related to "race conditions". Inside the ESP-IDF BLE classes there are multiple tasks in flight. I ...

[Question]: What is the "offset" parameter in the new BLE APIs?

In the latest client BLE APIs there is a new parameter found on some of the APIs called "offset". See for example:

esp_ble_gattc_get_all_char
esp_ble_gattc_get_all_descr

It isn't clear what this parameter means nor how it should be used. This question asks for additional clarification.

[Question]: Is the local cache ready to use after return from esp_ble_gattc_cache_refresh()?

There is a new API call called esp_ble_gattc_cache_refresh() that builds a local (to the ESP32) cache of the handles provided by the BLE server to which the client is connected. It is my belief that interactions at the BLE level are all asynchronous. My question is: "After the return from a cal...

[Question]: Do we need to call esp_ble_gattc_cache_refresh()?

Looking at the new API for BLE GATT clients, I see the new esp_ble_gattc_cache_refresh() API documented here: http://esp-idf.readthedocs.io/en/latest/api-reference/bluetooth/esp_gattc.html#_CPPv227esp_ble_gattc_cache_refresh13esp_bd_addr_t My question is: "Does this API have to be called after ...

Re: Write data to characteristic in Service Table

If you are willing to use C++ as opposed to C, I can possibly assist through the use of some BLE C++ wrappers ... see: https://github.com/nkolban/esp32-snippets/blob/master/Documentation/BLE%20C%2B%2B%20Guide.pdf However as of today (2017-09-23) there is a breaking change in the ESP-IDF that I am wo...

Re: Breaking changes to ESP-IDF BLE support and version management

Thank you sir ... that DOES help tremendously. In fact that is perfect. I think I am now seeing that the available documentation is generated based on the releases. So there is a set of documentation for each release and a set of documentation (latest) available for the Git master source. This is in...

Breaking changes to ESP-IDF BLE support and version management

Howdy Folks, I seem to find that there have been dramatic changes to the BLE APIs found in the ESP-IDF BLE support. See this commit log for details: https://github.com/espressif/esp-idf/commit/1759a47060e4708e264e11b395a0fbaeeca7863a The implication of this is that the applications written to the ES...
