Could you check the DFU Settings in the nRF Toolbox app? Please verify that "Packets receipt notification procedure" is enabled and if "Number of packets" are set to 10, then set it to 1.

I tried the change you suggested and I am still getting the GATT CONN TIMEOUT error.

Try to increase the connection interval by modifying the following defines in dfu_transport_ble.c from

#define MIN_CONN_INTERVAL                    (uint16_t)(MSEC_TO_UNITS(15, UNIT_1_25_MS))        
#define MAX_CONN_INTERVAL                    (uint16_t)(MSEC_TO_UNITS(30, UNIT_1_25_MS))

#define MIN_CONN_INTERVAL                    (uint16_t)(MSEC_TO_UNITS(30, UNIT_1_25_MS))        
#define MAX_CONN_INTERVAL                    (uint16_t)(MSEC_TO_UNITS(50, UNIT_1_25_MS))
