Problems with wlan and bluetooth under android

13 1530

i bought the Lemaker Guitare an i will use it with android. I have the version 1601 in the emmc. My problem is that i can't use wlan and bluetooth.

Is it useable in the 1601 version and my guitar is defective or has the wlan and bluetooth no function in this version?

Please help me.

I don't know much about ANDROID on Guitar, can you login via SSH (ethernet) ?
And if so, can you do a:
  • lsmod
  • iw list
  • uname -a
and post the results in a 'code' bubble.

If you are uncertain about the hardware, flash Lemuntu on it and do some checks.


thanks for your replay

I have installed Lemuntu. But there i can't use wkan and bluetooth too.

The wlan driver is showing with lsmod but in the wpa_gui tool it shows me no adapter and network.

Bluetooth is don't working too. The Bluetooth Manger shows me a failure at startup that he can't not connect to blue_z or so.

The normal network adapter is working.

lsmod shows

  1. pvrsrvkm
  2. drm
  3. owl_camera
  4. ctp_ft5x06
  5. atc260x_irkeypad
  6. wlan_8723bs
  7. ethernet
Copy the Code

iw list shows nothing

uname -a shows
  1. Linux Lemuntu 3.10.37 #2 SMP PREEMPT Sat Apr 16 02  11:06:24 CST 2016 armv71 GNU/Linux
Copy the Code

I see.
Did you install Lemuntu on the eMMC storage, this is important ?

Yes. Lemuntu is installed on the eMMC Storage. Also Android. All last three versions. No Wlan and
Bluetooth  at all. I think it must be a hardware problem.

I have it done but no luck. At step 4 it shows me no devices. Tomorrow i will send it back and hope a new one is better.

With the new board the problems are solved. It seems a hardware fault.

Thanks for your help
