Hi, I have just finished wiring up my section control via the arduino nano.
My tablet only has one usb port (HP pro x2 612)
I have to use a usb splitter.
When I don’t work with the splitter and only use antenna, it works fine, mostly.
When I add the splitter, with the arduino, i can rarely hold a gps signal, (box turns red).
Using COM4 @38400 for the F9P micro
Using COM5 for the arduino.
Can anyone recommend a usb splitter that should work, or is my tablet just not up to the task?
Could be bad contacts in the hub(spliter)
With USB as soon as you have a bad contact it disconnect I think. You have to reconnect manually.
It could also be that the two devices draw to much power from the tablet or hub.
When I was running with USB I modified the nano cable by cutting the red power wire.
I had a hub that had one port not useable because of bad contact.
That’s great info, thank you.
I will try modifying the cable and go from there.
You might need to power the relay board separately as i doubt you’ll get enough juice down the usb cable to run all that.
Rigging up the f9p to the ethernet port might help you and alot better connections aswell.
I did originally run the f9p and a nano very briefly via a usb splitter until i went the aio route.
Hmm, that won’t work for me. I have no ethernet port on my tablet.
Is the nano powered by 5v? Have you any suggestions on how to power this?
Thanks
Steven
The nano is powered by 5v i believe.
I used a 5v relay board but i powered that separately using a 12v to 5v converter then just used the nano for the switching signals but i was using a relay board for 12 switches aswell
Ok, it may be something i need to look into.
Thanks for your response
Depending how many relays you want to operate but id say the usb might be capable of possibly 1 or 2 but any more you might be struggling especially as your powering the f9p aswell.
Im sure there are ways around it and someone better suited than me to advise you.
