CCS/CC2640: immediate alert

Will Baker

Part Number: CC2640
Other Parts Discussed in Thread: BLE-STACK,

Tool/software: Code Composer Studio

How should immediate alert be implemented on a BLE client device? I've seen keyfobdemo and proximity for BLE server in DK. Example code would be appreciated. Thanks.

    You can revise key_fob example to send immediate alert when you detect something such as button press or GPI triggered.

    Hi Will,

    I don't understand your question. Can you provide some more detail?

    1. What version of the BLE-Stack are you using?

    2. What example project have you based your application on?

    3. What do you specifically mean by immediate alert?

    Hi Marie H.,

    Here are the responses to your questions:

    1) ble_sdk_2_02_02_25

    2) Proximity profile

    3) Immediate alert Service = IAS

    My device is a client (cc2640) that collecting measurements for a server (NRF52840). According to the developer of the server, AIS events are sent periodically to client device and I am not seeing them. So, I tried implementing code from the Proximity profile into the client: added callbacks, attributes, characteristic, etc and AIS events from the server are still being seen at the client.

    My next option is to have the serve to create a Generic Attribute Profile, and when the client sets CCCD = GATT_CLIENT_CFG_INDICATE send the AIS event (something of that nature).

    Am I making sense? What are your thoughts?

    Hi Will,

    Thanks for sharing more details about your use-case. 

    Do you have a sniffer so you can see what's being sent from the client? 

    Thanks, 
    Elin

    No, Immediate Alert should be like this. Why do you think you should use proximity profile for what you want to happen.
