Hi,
I've been implementing the BSP functions on a 15 button custom device based off of the nRF52832 (in a BL652 Laird Module). At a minimum I need to be able to disconnect the BLE and sleep the device (System OFF Mode). Right now I have the BSP_EVENT_DISCONNECT working fine. This works after a 1 second button press.
I'm having a lot of difficulty with the BSP_EVENT_SLEEP though. The only way I have been able to get this to work is through commenting out in my sleep_mode_enter() the bsp_btn_ble_sleep_mode_prepare(); This however doesn't allow a pin to be properly defined to wake-up the device, but all of the buttons wake it up.
/**@brief Function for putting the chip into sleep mode.
*
* @note This function will not return.
*/
static void sleep_mode_enter(void)
{
ret_code_t err_code;
err_code = bsp_indication_set(BSP_INDICATE_IDLE);
APP_ERROR_CHECK(err_code);
// Prepare wakeup buttons.
//err_code = bsp_btn_ble_sleep_mode_prepare();
//APP_ERROR_CHECK(err_code);
// Go to system-off mode (this function will not return; wakeup will cause a reset).
err_code = sd_power_system_off();
APP_ERROR_CHECK(err_code);
}
Every time I try to define a button to wake the device up from System OFF sleep on pressing it; when pressing the button associated with sleeping the device it immediately returns to a CPU on state pulling around 4 mA. The indication LED that I set up for the advertising mode will be blinking. If I comment out the above wakeup pin configuration the current drops to nA levels and the indication LED shuts off (as expected for sleep mode).
See the following code blocks for the main.c and bsp_btn_ble.c file contents and how the wakeup pin and sleep modes are enabled.
