use nRF Connect app to test Alert Notification client example failed

[tian]

My project based on nRF52832 and SDK is 12.2. I need to support alert notification(service UUID 0x1811) client profile for mobile device, I just build and download the nordic example ble_app_alert_notification to my board. My board works fine with other example like heart rate.

Next step I tried to find ways to simulate ANS server and comes to the nRF Connect mobile app, I got no 51dongle so I gave up the steps as the example test guide listed. Through the nRFConnect menu, select Configure GATT server->add service, then input "al", the list auto popped up a list with the first one is "Alert Notification Service", then I repeated to add all characterics:0x2A46, 0x2A47, 0x2A48,0x2A45, 0x2A44.

after that, in nRFConnect, can scan my board, but connect always failed. The board debug log printed: APP:INFO:Fast advertising APP:INFO:Start encryption APP_ERROR:ERROR:Fatal APP:INFO:Alert Notification started APP:INFO:Fast advertising APP:INFO:Slow advertising APP:INFO:Alert Notification started

Can someone give me a hint and really appreciate that.

Before connecting to the phone for the first time, make sure that the bonding information both on the phone and in the nRF52 device is deleted. Could you check if that changes anything?

After loading the Alert Notification Server file, click on "Connection map" and then the "peripheral" settings button.
