we develop 52832 from the project "ble_app_hrs_freertos" , in nRF5_SDK_14.2.0.
occasionally, xQueueSendFromISR returns without pdTRUE in Interrupt handler.
so xQueueSendFromISR should sent message to a normal task , but this make the program fail.
i try to put xQueueSendFromISR in a loop to retry 1000 times, this improve the problem, but occasionally , it get fail
i think there is enough heap and queue room. but what make xQueueSendFromISR wrong.
thanks for someone to give some guide
