Getting Started continued
EVDO910CF
• Enable the DVI interface and set it to master mode.
AT#DVI=1,2,1
• Set the interface type, and sample information.
AT#DVICFG=1,1,2,1,2
• Set the handset microphone gain.
AT#HSMICG=2
• Disable the handset sidetone.
AT#SHSSD=0
• Write the MAX9867 register information.
With the EVDO910CF, we can’t use the I2CWR command fully due to a current issue with multi-byte writing.
Example
AT#I2CWR=9,10,30,5,18 <-- This will return “OK”, but won’t actually work
Instead, we have to use it in single byte format if we want to use I2CWR, like below
Example
AT#I2CWR=9,10,30,5,1
Wait for response ”>” then enter the register information
>10
Press CTRL+z to send the information
Wait for response “OK”
The full flow of commands is as follows:
AT#I2CWR=9,10,30,5,1

AT#I2CWR=9,10,30,6,1

• Test the audio output by using a test tone generation.
AT#TONE=5,10
This will send out the DTMF tone for the #5 key press, for 1 second.
If the tone can be heard, the audio path has been set up and can now be utilized for voice calls or other purposes.
If the audio cannot be heard or is very quiet, the TSVOL command can be utilized to bring up the volume.
Example
AT#TSVOL=255,1,10
This adjusts all audio types, and a max value of 14 can be used. Please see the AT Command Reference for full command details.
