IoT SDK 0.8.0 NRF51422, Advertising on only one channel

[gecko667]

As previously seen on softdevices topics (devzone.nordicsemi.com/.../) I need to restrict BLE advertisement on only one channel for sniffing purpose.

The thing is, I cannot use the channel mask structure as indicated in the response of the question I refer to in the link.

Indeed, the softdevice version and its interface does not present the channel mask in the IoT SDK. I tried some integration of a regular Softdevice S110 instead of the one provided in the IoT SDK archive to get access to the channel mask structure, but it does not work (issue calling sd_ble_gap_device_name_set).

Do you have any solution I can use to advertise on only one channel with the IoT SDK, please?

The IoT SoftDevice is a modified version of the S110 SoftDevice v7.0.0 that doesn't support single channel advertising. This was first introduced in version 8.0.0.

What do you mean by sniffing purpose?

[gecko667]

My sniffer software is only able to sniff one channel at a time. Therefore I wanted to limit the adv and communication on only one channel as I could properly spy on. Otherwise this is a 1 over 3 chances to get a trace... which is not convenient for debug...

Thank you for your answer, this is what I feared...

Any update or merge planned? Any possibility to know which modifications have been made to S110 to obtain IoT Softdevice ?

It is mainly the added support of Connection Oriented Channels with the Credit Based Flow Control Mode, which is needed for transport of IP packets.
