How to use the android app control expansion pin(Nordic Thingy:52)

[sunnyvic]

Hi everyone I'm Rookie....

Recently bought this board, want to do more applications in the expansion of the pin, for example, control stepper motor or LED, but can not find the relevant development environment and grammar, can provide relevant information?

At the moment I downloaded Android SourceCode.

thanks

Hi!

Thingy lets you control the state of the Mosfets (M1 to M4 pins) over Bluetooth. This functionality is at present time not directly available in the Thingy mobile apps. Have a look here. If you write to the UI service: "EXT pin characteristic" (0303) you can change the state of these four Mosfets. I'd recommend you download nRF Connect to your phone, connect to Thingy and write different values to see the effect. If you want to develop FW for the Thingy itself, have a look at the code and documentation here.
