CC2340R5: Documentation for basic_ble_extctrl example

Part Number: CC2340R5


Tool/software:

I am curious about the new basic_ble_extctrl example in SDK8.40. What does this example do? Is it similar to AT command which enables a host MCU to control the BLE MCU? I cannot find any documentation for this example, where can I have the readme guide and the more details about commands format between the host and CC2340? I have a customer interested in such an example.

Best regards,

Shuyang

    Hi Shuyang,

    The initial example was not released with a readme. I believe your understanding is correct. Its similar to a network processor / AT commands use-case with more custom commands. I have reached out to R&D for more information, but in the meantime can you share the customers use-case? If they simply want to control the ble device from another device another option could be the ble_controller project which may be controlled by an external stack.

    Best Regards,

    Hi Jan,

    The use case is a UART-BLE bridge, but the stack needs to be run on the BLE chip, so ble_controller is not preferred.

    This use case also requires to configure the GATT table from the host MCU, which is not supported by our Data Stream UART over BLE example, therefore the basic_ble_extctrl example looks more suitable.

    Best regards,

    Shuyang

    Hi Shuyang

    Got it. Thank you for the additional clarity. In that case, then I do think the basic_ble_extctrl example would be the best bet.
