no link between tablet and 3dr radio

by timeee » Thu May 01, 2014 8:15 pm

Hi,

i've got a connection problem between tablet and 3dr radio v2, the module is connected to OTG port via supplied cable at the tablet.When i connect no permission dialog pops up. I have tested the radio on same tablet with android usb serial monitor lite from google play store.When conntecting in this app permission dialog for the usb device pops up, accept with yes connection is established. I can see data recieved from quanton flight control. Why does the Android gcs not connect to the radio module ? Can you help please me with this issue ?
thx

so that makes me think something about your radio has a different VID/PID that the other ones, which goes back to what I asked about if there is something different about the v2 radio? Link? Could you check the VID/PID when plugged into hte computer?

So if I give you the vid/pid of the xbee usb adapter do you think you might could see if you could get xbee usb to work with android gcs? Not that I expect you to fix it for every type but perhaps you could see if that is why it maybe will not talk to tablet. It works quite well with computer and I would love to see it work with my android devices. With computer, time from click connect to PFD and system monitor active is 4 seconds.

OK yeah. That should be easy. It is a different product ID and I think just adding it will fix that
