I'm have nRF52 DK, wish use nrfutil (v4.0.0) to update target firmware. Works fine when using -n "Target Name", but I get a "Device not found" when trying to use parameter -a "bluetooth_address" to specify target even though nrfutil displays message that an advertisement from this exact address is received. I'm connecting using the nRF52840 dongle which is fine when using nrfutil with -n "targetName" and when updating via DFU update such as in "buttonless dfu". I am using an address in the form "XX:XX:XX:XX:XX:XX", even tried without the quotes, but still get error.
My command line is nrfutil -v -v -v -v dfu ble -ic NRF52 -pkg apppkg.zip -p COM22 -a "XX:XX:XX:XX:XX:XX". Works fine when using nrfutil -v -v -v -v dfu ble -ic NRF52 -pkg apppkg.zip -p COM22 -n "MY_DEVICE"
