Hi Freescale


We tried to enable 3G module function in imx6.

Our 3G module is U6300.


I tried to merge (U6300-Android 4.2 version HAL layer) to Android 5.0.


When the system boot up in Android, I can get the information in Setting/About tablet/Status.    (include Signal strength ,cellular network type , Service state ,IMEI …… )


I  tried to link and setting APN.  Then system reboot.

( debug message will show option1 ttyUSB2: option_instat_callback: error -2 )


I tried to setting Airplane mode is enable.

I send command "pppd connect 'chat -v -s -t 10 "" "AT" "" "ATDT*99#" "CONNECT" ""' user username password password /dev/ttyUSB2 460800 nodetach crtscts debug usepeerdns defaultroute &"in debug console.

I can get ip address and ping google web is pass.


Do you have any advice about 3G function?
