[ble_app_uart] the nRF52 goes to sleep mode when there is no connection established

[Tai]

Hello everyone,

I'm trying to play with PPK II to check current using ble_app_uart example (nRF5_SDK_15.0.0). I notice that the nRF52 DEV KIT keeps advertising and if there is no connection established, the KIT will be under sleep mode (system ON mode). I can wake it up by pressing any button on the KIT. The following image showed what it happened (i.e., it was about 10.3 uA in the sleeping mode, and it went up to 2.65mA for advertising). 

My question is that which parameters control when the nRF52 goes to sleep mode? For example, after how many times the KIT advertising, it will go to sleep mode and could I control the number of times the KIT advertising?

Thanks a lot!

Hi,

Take a look at the top of main.c, and the APP_ADV_DURATION define. If you set this to 0 it will continue advertising forever.

Best regards,

Hi Stian,

Thanks a lot for your answer! 

I have posted another follow up question; however, you didn't reply it. I'll open another ticket for that.
