Failed to flash Auvisio URC-150.app IR Blaster

Hi,

I tried flashing an "auvisio URC-150.app" IR blaster. Model is NX-4519-675.
I can get the device to connect, but the flash process ultimately exits with a timeout message.
Any hints what I can try short of using serial usb to flash the device?

Start by reading the attached smarthack-mqtt.log, smarthack-psk.log, smarthack-udp.log, smarthack-web.log, and smarthack-wifi.log alongside the Auvisio URC-150.app model NX-4519-675. Done means establishing whether the timeout has a reproducible cause or workaround, and recording the device's support status for the described flashing path.
