nrfconnect dfu fail on andriod after paired

I was unable to reproduce this issue with the following setup:

SDK 11 bootloader and hear rate example extended with buttonless dfu support
nRF connect v.4.18.0 on Android
Paired phone with peripheral before initiating DFU from the hrs example

The GATT INVALID HANDLE error indicates that the phone is not doing a re-discovery of the attribute table upon entering DFU mode. I'd suggest to debug the bootloader to check if it sends the service changed indication from dfu_transport_ble.c::service_change_indicate(). E.g., check if m_ble_peer_data_valid is true and if sd_ble_gatts_service_changed() returns NRF_SUCCESS.-

I checked the keep bond information was enabled, but the same:

IOS it is always ok(after paired), but andriod always failed after it is paired, and always ok if it set to not paired

Hi Brian,

Please check if "keep bond information" is enabled in nrf connect -> settings -> DFU options. It should be by default.
