Thanks I will give it a shot … 👍🏻

I’m considering this possibility as one of the most likely now… I have an Alfa wifi adapter and I have already tried 5or 6 antennas and I never seen a performance boost … no matter how big the antenna I connect… Yeah some of them were hand made but I made sure to be precise… Here’s the link … It’s not my antenna it’s an identical one taken from the internet (the Alfa adapter is not the one I have … Mine is 2.4/5.8 and that’s exactly why you had problems I guess … )

Thanks man for the useful info what about where I connect the coax ? Does a different point in the same dipole makes a difference? I mean if it makes sense there’s a difference in connecting a coax to the top of the C or to the bottom ?

Update: can’t load the images some Lemmy errors pop’s up …

It’s a jst connector as others have already said you now can 1 stock up every jst known to man to have a chance of getting the right one … 2 just solder on the cables on the holes… In the right order …

Thanks so assuming the headphones use the USB battery charging standard ( just because I have measured only 5v output and it seems logical) how should I comnect up the second charger ? Do I still need to find the cc line (guessing a 5 v pin the closest to the USB port itself) and add a resistor ? The diode must be there in each case right ?

Are you sure ? How does a standard phone fast charge then , its not the case anyway cause the headphones regularly charge at 5v so it’s enough… Thanks anyway for your comment 👍🏻

Thanks so much for your help I will make some tests and hope for the best I now at least know that’s a lot more complicated that what it seems yeah definitely black magic to me too 😂 kinda ironic the universal name if u then have thousands of different standards

Hey I’m just scratching the surface of how deep this topic really is, I have read some articles and at this point I’m really confused, if I plug the USB cable in and search for 5v pads what will I found the vbus line which at the moment is the cc ? Or the d+ with the bc1.2 ? And how do I know what standard is it using at the moment ? Anyway from the wireless charger I only get 3 cables out 5v gnd and ID (keep in mind I have bought wireless chargers with the lightening plug because I wasn’t aware of such a complicated standard and they were cheaper anyway since now it doesn’t work I will bui proper USB c Qi chargers … ) So as I understood I should add a 5.1 k resistor because the charging board is expecting a pull down but I didnt get where … On the cc line ?

Yeah i have cheked and It only used 5v what did you mean by forcing AtoC cable ?

Thanks is there a way to know if the voltage spikes are properly filtered out without a spectrum analyzer I only have a multimeter ( and It shows something around 5v )I also noticed the coils will randomly die, I have altrady bought 2 from china and now I’m wondering if it has something to do with me charging the headphones via USB c while the coil Is plugged in … I Will add photos of the circuit as soon as possibile thanks again for your help

Thanks your comment is really helpful I will dig into the link you send tomorrow … In the meantime what is the likely solution to find a resistor and permanently solder it on the problem is that I would like to keep both USB and wireless charging options ( I don’t think it has any data capabilities) again thank you so much for your answer
