CC2640R2F: CC2640R2F ble5_simple_Central UUID Observation method and RPA usage method

규영 배
Prodigy 150 points
Part Number: CC2640R2F 
he current system structure is that the device measures eddystone RSSI data and transmits specific namespace data to the observer device when it reaches a certain distance. 
The current problem is that the BLE5 stack Central must be used to use the RPA function. Is this logic applicable to BLE5 stack central?


The namespace is structured like this:
 memcpy(rsp_data, pEvent->deviceInfo.pEvtData, pEvent->deviceInfo.dataLen);
 if((rsp_data[10]==0x53)&&(rsp_data[11]==0x61)&&(rsp_data[12]==0x6d)&&(rsp_data[13]==0x73)&&(rsp_data[14]==0x75)&&(rsp_data[15]==0x6e)&&(rsp_data[16]==0x67)&&(rsp_data[17]==0x45)&&
 (rsp_data[18]==0x64)&&(rsp_data[19]==0x64))

If possible, we will use the RPA function to inquire about using a whitelist so that only the relevant namespace can be searched.
thank you

    Hi,

    Thank you for evaluating the CC2640R2F and posting your question to the E2E Forum!  All of TI's BLE E2E Forum experts are taking a well-deserved time off on Friday, May 17th to Monday, May 20th and will be returning to answer forum posts on Tuesday, May 21st in the order and priority in which they were received.  Until then, here are some resources you can further consider which may resolve your issue independently:

    If you find the solution to your problem then please respond to this E2E post!  Otherwise, here is some additional information you can provide to best support the BLE E2E experts when they return to office:

    • SDK version being evaluated
    • Changes made to the default code example configuration
    • Your CCSTUDIO version and Dependencies installed
    • Any other screenshots, code snippets, or information which may prove useful.

    Thank you for your patience and diligence during this time!

    Regards,
    Ryan

    Hello,

    Thanks for reaching out.

    To make sure I understand correctly, could you please confirm that the idea here is for the peripheral to send a 20 bytes msg (rsp_data) after connecting to the central device based on the RSSI (distance)? Could you please explain a bit more about what the namespace is and if you are required to use RPA (for privacy purposes), please consider that for this to happen, the central and peripheral devices will have to connect and pair.

    You can look more into Privacy and RPA inside our User`s Guide.

    BR,

    David.
