nRF52840DK cannot sniff self-defined CSA

[BOZHENG]

Hi All

I am recently working on CSAs (Channel Selection Algorithms) in BLE on nRF52840DK, and I am using Zephyr to develop them. I have 3 nRF52840DK, one as sniffer, the other two as central and peripheral.

My sniffer would be able to follow the connection when I use both CSAs. But when I use my own CSA (I modified one of the CSAs in BLE by Zephyr), my nRF52840DK sniffer cannot follow the connection between central and peripheral anymore.

I would like to ask how I could sniff my self-defined CSA by nRF52840DK sniffer. Or is it impossible to sniff a self-defined CSA in BLE? Thanks in advance.

Hi, 

Unfortunately, the sniffer does not support custom CSA.

Hi Amanda

Thanks for your reply! If nRF52840DK sniffer does not support custom CSA, do you have any suggestion for me, if sniffing is a must in my test? Like other sniffers/devices? Test softwares?

Hi, 

I am sorry that we do not have released information about that.
