We want to designed a custom PCB using CYBT-423028-02 module and 10x2 keypad,
(1) How can we design a matrix keypad interface with ble module.?
(2) How can we wake a ble module on GPIO activity?
1. I would suggest you to go through the ble_keyboard application (\apps\demo\hid\ble_keyboard).
2. Please go through the low_power_sensor application (\apps\demo\low_power_sensor) to understand the sleep configurations.
Please check "wiced_sleep.h" APIs.
