Re: NVDS MAGIC FAILED issue with latest esp-idf

But we haven't use this NVDS right now This NVDS is used for store BT/BLE key and other things. If you don't care that automatically connect after reset, please ignore this log. So ...

Re: BLE characteristics value read/write operations
We provide two ways to decide the way of sending response by GATT server. One is sent by application by user, and another way is sent by low-layer stack. If use "esp_ble_gatts_set_attr_value", the low-layer stack will store the attribute value. But if you dont't specify low-layer stack send read/wri...

Re: BLE GATT server example: Service UUID not advertised
iPhone cannot realize service UUID of ADV_data. Because the ADV_DATA is only 31bytes. So you need to decrease the ADV_DATA size. In the demo, we do many settings of ADV_DATA for demo. So you can delete some settings of ADV_DATA. Thank you for chiming in. Sorry, this thread got a bit long, so it is ...

Re: Bluetooth LE APIs
Hi, for your questions:
1. We make ESP_api provide to users. BTA_api is for bluedroid internal. So users should call ESP_api, rather than BTA_api.
2. When newer version of ESP_IDF release, we will update some ESP_api.
