CC2640R2F: CC2640R2F

Hello,

What is the minimum interval at which we can advertise the packet in BLE 4.2. We have taken the simple peripheral example of BLE 4.2 and tried to send the data at various interval. We were able to reduce the interval to minimum of 25 ms which corresponds to 40 counts in the code. Reducing it further has stopped the advertisements completely.

Also, is there any difference in the interval for BLE 4.2 and BLE 5 various modes (2 Mb/ coded Phy)

Similarly, what is the minimum scan window supported in the BLE observer at which we can keep practically for BLE 4.2 or BLE 5

Regards]

    Hello Prateek,

    For BT4.2 stacks, connectable (excluding directed) ADV max rate is 20ms and non-connectable is 100ms.
    For BT5 stacks, both connectable & non-connectable are 20ms max rate.

    Please see the CC2640R2F Scanning & Advertising SimpleLink Academy Labs on TI Resource Explorer: dev.ti.com/tirex

    Best wishes

    Hi,

    You should find the answer here for BLE 4.2:
    dev.ti.com/.../

    For BLE5 the advertising interval range is 20 ms to 10,485.759375 s,
    and the scan interval and scan window ranges from 2.5 ms to 40.959375 s.

    Best wishes
