I just bought a Tinkerboard 2s and the wifi and bluetooth is not working. 

1  Is the hardware bad or does the tinkerboard OS 2s newest installation need to be fixed?

2  Will an older version work?

3   I don't know if it is that software drivers need an update.  I don't want to send it back and buy another one just to find out that this one has no hard ware problem.

4  Has anyone get the bluetooth working in the TB2s?

I searched the forum and found nothing about bluetooth and wifi.  

 

I installed this one and tried the newest android.  No bluetooth and wifi.

Hey Jay,

Did you install to the emmc or a sd flash drive? (is the emmc in parked mode?)
Have you tried re-flashing/re-installing?  ?

I had a similar problem that were related to build/compile errors at install.

Re-flashing, installing then re-configuring fixed it for me. ?

I installed to the emmc.  What is parked mode?

I will flash to an ssd and see if the bluetooth works.

So, you're bluetooth is working on a tinkerboard 2s with the tinkerboard 2 debian 10 os?

I tried android os and no wireless network seen.  It's not seeing the router.  And no bluetooth connection to devices.

I will return it. 

They sent me a new tinkerboard 2s and it's the same no wireless and bluetooth.

Can you help me get it configured?

I found this and was able to disable the Sap Driver.  But, bluetooth still not working.

SAP stands for SIM Access Profile, so you have to disable it:

    Open /etc/systemd/system/bluetooth.target.wants/bluetooth.service

Change:

    ExecStart=/usr/lib/bluetooth/bluetoothd

To

    ExecStart=/usr/lib/bluetooth/bluetoothd --noplugin=sap

Reload the systemd:

    $ sudo systemctl daemon-reload

Restart the bluetooth:

    $ sudo service bluetooth restart

Get the bluetooth status:

    $ sudo service bluetooth status

I found out what was the problem.  I finally connected with bluetooth.  However, the bluetooth device has to be within 1 foot of the Tinkerboard 2s.

One foot?

It looses connection if further away.  So this TB2s has a one foot range for bluetooth.

I assume the wireless has to be one foot from the router to connect wirelessly.

How can you fix something like this?

The wireless would need a wireless extender right next to the TB2s.

Any suggestions for bluetooth?  Does the bluetooth need the antennas connected?  I think that is only for wireless internet.

Yes, the antennas must be snapped on the wifi/bluetooth circuit board that is screwed down on the TBs2 board.  Wifi and bluetooth is working.
