EXT GPIO pins on THINGY52 as a service

Hi Hung,

Thank you for the response. To confirm, yes, I am using the 'canned' service for EXT pin characteristic from within nRF connect mobile app to operate the MOS_1 to MOS_4 with success.

Form your response, I see a 'canned' service to configure and read/write the EXT.0 thru EXT.3 pins will need to be coded... to be modeled like the button characteristic UUID:0302.

Thanks for your assistance.

-Doug

Hi Doug,

Just to clarify you are looking at the "EXT pin characteristic" UUID:0303, which control pin MOS_1 to MOS_4 ?

By default they are output pins. But it's up to you to modify the code to make them input pins. The configuration is m_ui_init(). The characteristic currently supports write request and read, you would need to add notification feature like the button characteristic UUID:0302.
