Hi! I am testing the UART of the ESP32 with this configuration: 9600bps, 8bit, No parity, 1 stop bit and no flow control. I have used the uart_events_example as a reference. Everything starts ok but after some minutes I start receiving the event UART_FRAME_ERR from the uart. My doubts are: What is t...

Hi to everybody, Regarding to the latest news about Bluetooth and its new version BT5.0 that has interesting new features compared to actual 4.2 version: • 2x Speed • 4x Range • 8x Data I would like to know a bit more about ESP32 roadmap.  Is ESP32 going to support any of this new features?  Will ...

I think that some examples about GATT Server and client would be great to understand how to manage the stack and it features. Also taking into account security and different ways of pairing/bonding. This kind of high level examples focused on BLE GATT server/client will make it easier any develop on...

No one from Espressif can answer this doubts/questions?

Hi, After exploring into the esp-idf and its files/examples, I haven't found any reference to Bluetooth SIG specified GATT Services like Alert Notification Service, Battery Service, Current Time Service, etc. My doubt is about if espressif is going to facilitate examples or code to implement these a...

Hi, Starting from bluetooth/gatt_server example I have make some modifications to achieve a 'propietary' service that is composed of a characteristic and its client characteristic configuration descriptor (cccd). From the client side I am able to read/write values into CCCD to enable notifications o...

Thanks ESP_Tianhao, Now it is clear! Once I have set "esp_attr_control_t *control" parameter on "esp_ble_gatts_add_char" function call, read/write operations works ok and autonomously managed. Without setting this parameter like you said our app has to manage read/write operations with ESP_GATTS_REA...

Hi, I am working on the gatt_server example. I have modified the code to define a 'propietary' (128bit UUID) with a characteristic. When callin esp_ble_gatts_add_char function: Permisions: ESP_GATT_PERM_READ | ESP_GATT_PERM_WRITE Properties: ESP_GATT_CHAR_PROP_BIT_READ | ESP_GATT_CHAR_PROP_BIT_WRITE...
