NRF_GZLL_MODE_SUSPEND nRF52 SDK 15

[BrianK]

I would like to use Gazell along with BLE using the TimeSlot API. As part of this I need to set the Gazell mode to NRF_GZLL_MODE_SUSPEND while waiting for the next timeslot.

I've adapted the examples from the nRF51, and it looks like I have one problem to solve before it will work.

The problem is that whenever I use 

nrf_gzll_set_mode(NRF_GZLL_MODE_SUSPEND);

The call does not return error, but the mode does not change to suspend mode, and always remains 0 (device mode).

Also I never get a nrf_gzll_mode_changed() callback when trying to change the mode.

Gazell is enabled at the time I try to change the mode.

Is there something else I need to do to be able to change Gazell mode?

SDK 15.0.0, SD S132, nRF52832

Thanks,

Brian

Hi Brian,

 

I think the problem when using the sd_resources library is that it also uses TIMER0 internally in the gazell library, and you're also using it in the timeslot.

Could you please try to use the other library and see if this has any impact on the mode switching?

 

Kind regards,

Håkon

Hi Hakon,

Ok I tried this again. It turns out that the SD fault I mentioned with the gzll_nrf52_gcc.a library was my coding error. My understanding of how the two libraries worked was reversed. It would be helpful to have more documentation around this, but I'm glad that the feature has been carried over from the nRF51!

Anyway I am successfully able to use Gazell (device mode) and BLE concurrently now on nRF52.

Thank you for the assistance.

Brian
