External antenna TTGO T8 #9

Open Civilduino opened 4 years ago

Civilduino commented 4 years ago

I got the TTGO T8 V1.7 20180721 and I will like to use the external antenna connector. Is it just to plug the antenna?

I tried that I don't think it is working. Do I need to solder some resistor, cut a trace? add a jumper?

Without the antenna the board is useless for my application.

Thank you for clarification and improving the documentation. Some pictures of what to do should be good.

I am having the same question. Looking at the schematic I would assume that you have to desolder R16 and bridge R23 (or use the desoldered 0Ω resistor). It would be nice to get some clarification on this though.

Did you ever get an answer to this

LiveRock commented 3 years ago

Any answer to this? I bridge R23 with a wire (not resistor) and the performance because much much worse even with an external antenna...

KuhlTime commented 3 years ago

Sadly I did not get an answer. My performance decreased as well when I tried that.

Maybe good to point out that there is another question regarding the IPEX antenna: https://github.com/LilyGO/TTGO-T8-ESP32/issues/20
