Hi,

What Softdevice version are you using?

For some reason I get stuck in softdevice at 1EA7A when a send some random data to my phone also I notes that function sd_ble_gatts_hvx return 3401
As you say, an assert at address 0x1EA7A originates inside the Softdevice, but error 3401 occurs in the application. Are these unrelated incidents? If so, what are the circumstances around the two errors. 

Error 0x3401 is BLE_ERROR_GATTS_SYS_ATTR_MISSING, and is a common topic here on devzone: https://devzone.nordicsemi.com/search?q=BLE_ERROR_GATTS_SYS_ATTR_MISSING.

 

Best regards

Martin

I am using softdevice 5.1.0 and there related incidensts. And It happens when enable the notification from the phone side
