CC2640R2F: Master-slave connection

Part Number: CC2640R2F

Hi team,

   My customer once use CC2640F128 Master/slave example and met a problem. The master node start to observe, searched the slave and then connect, in this case, the master node frequently can't connect with correct slave. But when pre-program the slave address in the master node, the connect is 100% OK. SDK version is ble_cc26xx_2_01_01_44627.

   When we use CC2640R2F + simplelink_cc2640r2_sdk_1_40_00_45, the issue never turns up even we don't pre-program slave address. CC2640F128 and CC2640R2F share the same hardware design.

    So what is modified in the two versions of SDK that may influence the master-slave observation and connection?

    Hi Holly,

    There has been lots of changes in the SDK from BLE 2.1.1 till now where we introduced RF driver, improved RF driver and fixed BLE STACK bugs. It's hard to compare these two versions. All the bug fixes are in the release note which comes together with the SDK.
    Also are they using custom HW?
