Completely disabling sleep mode

[Scott]

I am using the ble_app_uart example as my base on a 52832 with sdk 12. My project runs off line power and needs to remain available for connection 24/7. I have commented out BLE_ADV_EVT_IDLE case in on_adv_evt() function and the BSP_EVENT_SLEEP case in bsp_event_handler() function.

LED 1 blinks indicating that it is advertising, and for a few minutes it is visible in nRF Connect. But, after approximately 5 minutes the device is no longer visible. However, the LED continues to blink as though the device is still advertising.

Is there something else required to disable sleep mode completely?

Are you doing unlimited advertising(BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE) with timeout set to 0?

That was it! I completely overlooked the advertising options. Thank you Daniel
