This is very simple wearable device with a push button for emergency contact application. Click/double click/long hold will trigger app(android/ios) to SMS/Call friend/911. I have already hardware and schematic, pcb circuit. I only need firmware. 1. click = sms 2. double click = call family 3. long hold = 911(emergency) here, 911 = phone number for medical emergency Nrf52832 sends signal(click/double click/long hold) to mobile app via bluetooth interface. In generally, nrf52832 is in sleep state. If you will click the button, 52832 wake up from sleep and send certain strings to mobile via bluetooth. For example, if you click one click, 832 send 11, if you click double click, 832 send 22, if you hold longly, 832 send 33. Pin for button can know from schematic schematic. source code : [login to view URL] apk: [login to view URL]
