screen or minicom comes to mind.
for that, simply short the Rx and Tx pins on the Pi.
this seems too hard for me, I decided to buy a cp2102 with jumper pin connector, that way it would be easier for me.
For now if you can help me debug this router without opening using any dumper or listener it would be helpful thanks.
incase if I get to buy pins tomorrow I connect to debian raspi and try to work it out, it its hard, i will buy a cp2102
I soldered the pins they are tight I guess, I am not that much good at soldering. Can you check if this will do? The pins dont fall of loose and I think its Ok? I guess
I think your soldering can be improved by just a few minor adjustments:
As you are soldering pin<->PCB(board), make sure, to not just heat up the pin, but instead heat up the joint point of PCB and pin. It is a key point, to properly heat up the PCB. So rather touch the tip of the soldering iron to the PCB right next to the hole, while also touching the tip to the pin, but mostly concentrate on the PCB and not on the pin, the pin will usually catch sufficient heat.
(At least your current soldering result looks like that the PCB did not get enough soldering heat)
Make sure to have a small electronics soldering iron with a pointy tip. Remove black dirt from the tip, as dirt blocks heat transfer.
If this adjustment to get proper heat to the PCB does not help, check if your soldering tin wire has integrated soldering grease. If not, apply a bit of soldering grease (it will flow to the right spot on its own). But usually its the proper amount of heat at the right spot that does the important part.
Some more optional things:
- maybe you are having a soldering tin wire that is a bit thick. Thinner tin wires are easier to dose the right amount of soldering tin to the target. Maybe get a thinner one for your next projects.
- dont add any more soldering tin to the left or right pin. If you follow my tips above, you may have a small risk of unwanted connecting pins via solder tin, as you have a large amount of soldering tin already on the left and right pin. If any such unwanted shortenings happens, have some desoldering braid at hand, to undo the shortening.
- if you need to apply more tin, dont aproach with the soldering tin wire to the heated up pin. Instead heat up PCB + pin with the iron first and then approach the tin wire to the soldering iron, anyware close the iron tip. If everything is heated up properly, the tin will insta-melt and flow via soldering iron right to the required spot on its own, creating nice soldering spots.
- If you are scared of damaging the PCB by heat, make a short pause between different attempts. But it looks like you do need more heat to the PCB than in your previous attempts.
I can highly recommend, check a few Youtube tutorials about soldering, until you find a good one.
And practicing this for 15-20 minutes on a scrap PCB does a lot of improvements.

i sticked to paperclips again, it went loose and soldering didnt stick to it
is this the Pi GPIO ?
Yupp its in the gpio ports like as told before
this time I tore it down because last time it was hard, after asking my aliexpress seller they said its okay to open the case for fixing if it doesnt work they told me to send it back to them.
serial0, according to https://www.mathworks.com/help/supportpkg/raspberrypiio/ug/use-the-serial-interface-on-raspberry-pi-hardware.html
I think you said AMA0 it works, (not connected to router yet)
short the Tx and Rx pins, you should see your own typing in the terminal app.
if you do, your setting are correct.
it does but now how to use it with router
?
so the port is correct.
then hook up the router instead.
it shows nor offline like it normally does
minicom -b 115200 -D /dev/ttyAMA0
