sleep mode during multiprotocol timeslot API

[Constantin]

Hi,

I've just started to implement the example

github.com/.../nrf51-ble-micro-esb-uart

for the nrf52. And it is now running so I can send and receive stuff via BLE and at the same time send something via ESB to a RTX board. The problem is with this example that the BLE advertising times out after 180 seconds and then goes into a sleep mode with sleep_mode_enter.

But from my understanding this will force the softdevice to go into sleep mode. But then ESB won't work either. Is there a way to put the soft device into sleep mode where it only wakes up via a button press or something and at the same time keep the timeslot running for the ESB. Thanks a lot and best regards,

Constantin

sleep_mode_enter() will call sd_power_system_off(), which will put the chip in system off. This is not something you want if you actually want to do something.

It should be sufficient to call sd_app_evt_wait(), which is done by power_manage() in the main loop.

So I recommend to just not call sleep_mode_enter() on when you get the BLE_ADV_EVT_IDLE event.

Dear Petter, yes this is what I am doing right now. But If I do not restart advertising with: ble_advertising_start(BLE_ADV_MODE_FAST) the timeslot is not triggered and the ESB dies as well. But from my understanding this could not be the solution. I want to stop advertising but keep esb running in its timeslot.

That shouldn't be the solution. Could you share your complete project with me?

Please find attached the current version of my project. I am using eclipse without Makefile and SDK 13. ble_esb_project.zip

I am setting P.02 to HIGH during the timeslot IRQ Handler.

What happens if you don't call ble_advertising_start() in your main loop? The same behavior?
