The ble_app_gls example does not provide any handling code for BLE_GAP_EVT_TIMEOUT, BLE_GATTS_EVT_WRITE, nor BLE_GATTS_EVT_HVC. I'm trying to understand whether the lack of handling for these events creates any potential issues we need to be aware of? I can guess as to the causes and response to the timeout, but am not clear on what if any handling is appropriate for the other two?
