User Manual

This command must be used only to gather information on network name and signal strength,
to check if mobile is registered or is looking for a suitable network to register. Always use the
+CREG command. This is due to the fact that if the network signal is too weak and mobile
loses the registration. Until a new network is found the #MONI command reports the last
measured valid values and not the real ones.
The TA (timing advance parameter) is valid only during a call.
To properly use this feature, check network registration with command +CREG as seen on
par. 2.7.3.1 and when mobile is registered query the mobile for network operator name and
signal strength with #MONI command.
Before a voice call can be placed, it is recommended to check if the mobile is registered on a
network (see par. 4.4.3.1) and if the signal strength is enough to ensure a call can be made.
 send command AT+FCLASS=8<cr>
 wait for OK response
This command may be omitted if the modifier ";" is added at the end of the ATD command
after the dialed number.
The HE910V2 family has three different audio paths:
 PCM microphone/ear(PCM)
Usually the internal path is used for a handset function, while the external is used for
handsfree function. There are two ways to switch between these two paths:
 SOFTWARE: by using the command AT#CAP= <n> (with n=1 OR n=2)
 HARDWARE: by setting AT#CAP=0 and setting the AXE input high (internal
MT) or low (external HF).
If only one path is needed, then it is preferable to use the internal one (MT).
When Hardware control is not needed AXE pin can be left unconnected.
The audio paths can also be switched in both ways during a call.
