hi, I'm trying to connect my w8980 router by serial interface. I use a ttl to USB dongle cp210x (I tried also a prolific 2303) and I always got the same result in my serial console (either screen or putty) I mean unreadable characters filling the console. I use TX RX and ground, 115200 8N1. I'm short on this so I need some help.
anyone has encountered such issue ? I'm already stuck at the very start of the process !
I fixed the issue by re soldering properly the leads to the boards. obviously the contacts were bad. now it works fine. I didn't Believe it could be the way I soldered them but it was.
