dfu gatt error

[james]

hi: I use bootloader example of sdk 9.0.0 ,most cases worked fine, but I got gatt error sometime when I begin DFU. I had changed the dual_bank_ble_s110 into sigle_bank_ble_s110.Did I miss something here?

Are you seeing this issue if you use the dual bank bootloader? You could try to increase the connection interval and see if that helps, i.e. edit the MIN_CONN_INTERVAL and MAX_CONN_INTERVAL defines in dfu_transport_ble.c.
