Yihui Xiong / Mbed 2 deprecated BLE_Default_APP

BLE FOTA APP

Dependencies:   BLE_API mbed

It doesn't work with the default FOTA bootloader. It use NVIC_SystemReset() to enter a bootloader.

yihui 1:a607cd9655d7 19 * @brief Application timer functionality.
yihui 1:a607cd9655d7 20 *
yihui 1:a607cd9655d7 21 * @details It enables the application to create multiple timer instances based on the RTC1
yihui 1:a607cd9655d7 22 * peripheral. Checking for timeouts and invokation of user timeout handlers is performed
yihui 1:a607cd9655d7 23 * in the RTC1 interrupt handler. List handling is done using a software interrupt (SWI0).
yihui 1:a607cd9655d7 24 * Both interrupt handlers are running in APP_LOW priority level.
yihui 1:a607cd9655d7 25 *
yihui 1:a607cd9655d7 26 * @note When calling app_timer_start() or app_timer_stop(), the timer operation is just queued,
yihui 1:a607cd9655d7 27 * and the software interrupt is triggered. The actual timer start/stop operation is
yihui 1:a607cd9655d7 28 * executed by the SWI0 interrupt handler. Since the SWI0 interrupt is running in APP_LOW,
yihui 1:a607cd9655d7 29 * if the application code calling the timer function is running in APP_LOW or APP_HIGH,
yihui 1:a607cd9655d7 30 * the timer operation will not be performed until the application handler has returned.
yihui 1:a607cd9655d7 31 * This will be the case e.g. when stopping a timer from a timeout handler when not using
yihui 1:a607cd9655d7 32 * the scheduler.
yihui 1:a607cd9655d7 33 *
yihui 1:a607cd9655d7 34 * @details Use the USE_SCHEDULER parameter of the APP_TIMER_INIT() macro to select if the
yihui 1:a607cd9655d7 35 * @ref app_scheduler is to be used or not.
yihui 1:a607cd9655d7 36 *
yihui 1:a607cd9655d7 37 * @note Even if the scheduler is not used, app_timer.h will include app_scheduler.h, so when
yihui 1:a607cd9655d7 38 * compiling, app_scheduler.h must be available in one of the compiler include paths.
