In my application, I need to use the nrf52840 for both BLE (as the controller) and ShockBurst. Specifically, it's the nrf52840 on the nrf9160 if it matters. I'm using the zephyr BLE stack and things a

Good question, there exists an issue that can be used for this discussion: https://github.com/zephyrproject-rtos/zephyr/issues/7092 ________________________________________ Sent: Wednesday, September

Hi Sebastian, Robert, Sebastian, thanks for pointing out the existing issue. Robert, would you please comment on that issue stating the needs of your application so we can evaluate how best to fix thi

Hi, The pre-programmed PPI are very specific to Nordic's in-house stack implementation needs. Some of them coincidentally can be re-used in Zephyr implementation. I will try to send a PR by EOD, if it

Hi, Only 5 of the pre-programmed PPI can be reused in Zephyr's BLE implementation. But the task to refactor the controller is not simple (i.e. not doable in a day or two). In upstream Zephyr, PPI's 16

Hi Henry, This is news to me and, although it might be expected, I would like to check with a couple of people. So I think this deserves being tracked. Would you mind opening a “Question” issue on Git
