How can I change UUID or Major/Minor numbers once a GPIO is toggled? i.e. dynamically during normal advertisement. Is there any example in the SDK?

[Avi]

Once GPIO is pressed (shorted to ground), I want to change the value of UUID or Major/Minor number

If not, the device will continue to advertise the previous values

Hello,

You will need to detect the button press. You will find examples doing this. E.g. the examples found in:

SDK\examples\peripheral\pin_change_int

SDK\examples\peripheral\bsp

 

Then you need to change the advertising data. You can do this by using the sequence: Stop advertising -> advertising_init (with your new advertising data) --> start advertising

 

Unfortunately, we do not have any examples doing exactly this at this point in time.

 

Best regards,

Edvin

Thank you - works perfect!

I found that using the pin_change_int example, the current consumption is too high.  Where can I find an example of using "Sense" approach?

I found the answer: Just change to false: nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(true);

to: nrf_drv_gpiote_in_config_t in_config = GPIOTE_CONFIG_IN_SENSE_TOGGLE(false);
