Unexpected BLE_GATTC_EVT_HVX

[Noon]

Hello,

My firmware is based on the ble_peripheral_HID_mouse (nrf52 DK, pca10040e_s112). I receive unexpected BLE_GATTC_EVT_HVX events of indication type from Client side (Android nrf Connect). Even if i disable Server configuration into the nrf Connect App...

So, i need to respond to this (mysterious) event to avoid a disconnection (GATT ERROR 0x16). I think this is a model phone issue, because this behaviour doesn't happend with samsung but with oneNote devices. This problem is related to this case: https://devzone.nordicsemi.com/f/nordic-q-a/30804/nrf-connect-for-android-disconnects-with-error-22-gatt-conn-terminate-local-host

Someone know what happens?

Hi,

Someone know what happens?

Do you have a spare DK, so that you can do a sniffer trace? See this link: https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE
