Bitbanging from TIMER1 when using SoftDevice

[Shlomo Zippel]

Hello,

I know I'm not supposed to use TIMER1 with IRQ 0 when using a SoftDevice but I want to try anyway :) I want to do some bit banging with timing that is timing sensitive and can't be delayed by the SoftDevice interrupts.

Did anyone try this? Is there any tolerance at all or is the SoftDevice guaranteed to fail with a timer running at priority 0?

Thanks

The sotdevice is guaranteed to fail if there is any BLE activity going on and this will happen as soon as your timer interrupt (which delayed softdevice IRQ handling ) has finished. Use Timer0 in Timeslot API which you can use with highest priority. What is the frequency of the needed bitbanging?
