TCP or UDP protocol when downloading firmware?

Hello everyone,

I have a question: When downloading Trezor model One firmware from the internet (while setting up in Trezor suite), does it use the TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) protocol? I ask because my internet is bad. And I’m worried that the firmware won’t be fully downloaded if packet loss occurs.

Thank you in advance.

Obviously tcp , when downloding ,you can grab the packets to confirm .

it’s downloaded using regular https, which runs over tcp.

in addition, Trezor would refuse to install the firmware if it got corrupted anyway.
