why is my system resetting every minute or two when i call "sd_ble_gap_adv_start"?

[luke]

i couldnt find any question related to my specific problem.. when i call that function my system is resetting after a minute or so and sometimes it is shut off. i am using a custom made prototype not the dev kit.. the problem is i have a few prototypes and the dev kit but only one prototype is acting up like that. not sure of which sdk in use here for i am not the only one working on the prototypes.

the same code is applied on all. so would be possible that it is a chip version that is differing? im not sure what the problem is but it goes away when i comment out the "advertising_start()" function or this part of it "err_code = sd_ble_gap_adv_start(&adv_params); APP_ERROR_CHECK(err_code);"

thank u in advance for ur help

Hi,

The default advertising time is 180 seconds:

#define APP_ADV_TIMEOUT_IN_SECONDS      180

After 180 seconds you get the advertising timeout event, and the chip will try to enter sleep mode. If you are in debug mode, the chip will reset. See here for more info on this. You should power-cycle the device after you have flashed the device.

i just recorded the time in seconds between each reset and it is exactly 60 seconds its not 180 seconds

and APP_ADV_TIMEOUT_IN_SECONDS is 180? It has not been modified?

[luke]

yeah its 180 untouched.. i modified it and the result is the same.. so i dont thing its the case.. i returned it to 180 at the end. also i power cycled it but no fix there =/

Ok. You could try to find the reason for the restart by debugging. See this thread.

could it be a defective unit? i mean other prototypes and the dev kit do not exhibit the same issue. and im using the same code.. it seems an error check is causing a system reset gonna try to pin point the problem.
