nrf51822 and Gazelle with softdevice

[Plutok Oleg]

Hello

SDK12.3, nRF51822

Example Gazelle from SDK works fine.
If I use the softdevice (add ble_stack_init) then the program freezes in the nrf_gzll_enable

Hi,

 

Both the Softdevice and gazell tries to use the same resources, such as the radio, timer, and software interrupt. This will cause a collision, and therefore it stops working.

You can use a feature in the softdevice called "timeslot" to run gazell in between your bluetooth events. Here's a tutorial:

Another approach that is not that dynamic is to disable the softdevice then enable gazell (and vice-versa if needed).

 

Best regards,

Håkon
