High priority for specifed peripherals using Timesolot s110 v.80

[Nicu]

Hello, I use nrf51822 as peripheral and after connection with central module(nrf51422 dongle) I want to set a period(10 s or more than 10 s) in which Softdevice will have a low priority, and a specified pin will have a high priority. I read a little about Concurrent Multiprotocol Timeslot API, and I understand that I can do this using sd_radio_session_open() ,sd_radio_session_close() and sd_radio_request().It's this possible? Exist an example for this?

Thanks a lot ,Kenneth

I read this tutorial and I have a problem, I receive NRF_EVT_RADIO_CANCELED event every time after initialization of timeslot(timeslot_sd_init()).It's posible to be afected by the connection with central module(nrf51422 usb dongle) when I request a timeslot?(I use s110 v8.0 for peripheral and s120 for central).

In the Softdevice Specification for the the specific S1xx release you should find a chapter named Multilink scheduling. There you can find what priorities can preempt a scheduled timeslot. I suggest you can either try to increase the priority of the timeslot to high and/or schedule a new timslot when you receive NRF_EVT_RADIO_CANCELED.
