trying BLE and ESB parallel - SWI0 and radio

[ricardo_marinheiro]

Hi, I'm trying to run ESB during the timeslot api requested slots. The problem is that BLE uses app_timer, which uses SWI0 for the callbacks, and at the same time, ESB also uses SWI0. As soon as I compiled the code, no surprise, it complains that there is a redefinition for the SWI0 ISRoutine.

._build\ble_app_hrs.axf: Error: L6200E: Symbol SWI0_IRQHandler multiply defined (by nrf_notification_manager.o and app_timer.o).

Is there any chance to make ESB use another method ( for callbacks I presume...) than SWI0?

Very much appreciated for the help.

P.S.: Not sure if this could actually work, once I have a feeling that re configuring the radio for the ESB might mess up the BLE work. If This is the case, please advise.

You can redefine which interrupt to be used by the ESB, that's not a problem. Just make sure it's given the highest priority during the timeslot event. You can't have ESB and BLE running at exactly the same time, so you can only use ESB inside the time slots that you are assigned.

Are you using Radio Notification? If not, you can re-use the SWI setup towards Radio Notification. I'm not sure if you have had a look at the code examples showing usage of S110 with ESB/Proprietary radio in time slots: github.com/.../nRF51-multi-role-conn-observer-advertiser

If you don't hand control over to the BLE softdevice at the end of the time slot, the BLE connection will fail. You will drop the link, but the application shouldn't fail. You could do a re-connect. This isn't recommended, you should disconnect and disable the Softdevice if you think that you have to use more than what you are give as time slots.
