S42: the AT instruction in step A is executed, the dtmf tone frequency signal testing function of caller module is in the open state, i.e.,
Dtmf tone frequency signal is detected；
S43: user's result answer code can be obtained in caller module after detection, obtaining user's result answer code can determine whether
The audio of module to be detected is normal.
User's result answer code, that is, URC；
It is effective for actually proving to return, or detection calling terminal has the sound that delay is returned.Dtmf tone frequency only can be
Called end has sound, and only has URC detection to report in called end, therefore simulate proximal end (called end after being shorted) and be sent to master
That cries end has the URC returned and the sound returned, and theoretically, URC normal audio will be normal, to verify audio uplink and downlink just
Often, this is also a kind of mode of detection in fact.Furthermore it can also realize that detection URC is reported for verifying long-term pressure by script
Equipment audio in power is normal.
Realize the process that reports of detection URC by script the following steps are included:
S501: caller module and tested module are separately operable dial peer script and receiving end script；
S502: caller Module cycle handover network standard, under non-GSM network state, caller module dials tested die trial
Block, tested module are connected, and caller module sends dtmf tone to tested module with the instruction type of AT+VTS after 2S；In GSM
Under network state, caller module sends audio file to tested module with the instruction type of AT+QPSND after 2S；
S503: tone testing is carried out
After caller module detects the URC of correct dtmf tone, otherwise tested module kill-call stops script and retains
Scene.
The present embodiment has also done following verifying, comprising the following steps:
S601: input and output pin are shorted
Before being tested, the MIC on called end is shorted with SPK pin, such uplink and downlink voice will form one
Circuit；
S602: voice communication is carried out
Calling terminal dials called end, carries out voice communication；
S603: tone testing is carried out
No matter the voice that calling terminal is sent is the dtmf tone frequency signal detected with user's result answer code or common
Audio signal can only hear noise in calling terminal, therefore being in the case where being not turned off echo restrainable algorithms can not be to uplink and downlink
Voice carries out verifying work.
The present embodiment additionally provides a kind of test macro of automatic detection uplink and downlink voice, comprising:
Short circuit module, for the MIC in module to be detected to be shorted with SPK pin；

Answer code；
Short circuit module, algorithm closedown module, voice call module are electrically connected with audio-frequency test module.
It should be noted that being that be inhibited with one property of echo, meeting by echo due to the sound returned from tested module
Algorithm completely eliminates, we just have no idea to detect dtmf tone frequency signal in caller module in this way, and caller module is heard
It is exactly some noises, can solve this problem after executing order AT+QAUDMOD=3 in tested module at this time.
Echo restrainable algorithms are a kind of echo control algolithms earlier.It is a kind of nonlinear time based on sound echo suppressing
Sound is eliminated.It by simple comparator will prepare the sound played by loudspeaker and the pickup of current microphone sound level into
Row compares, if the former is higher than some threshold value, allows for reaching loudspeaker, and microphone is closed, to prevent it from picking up
Loudspeaker play sound and cause far-end echo.If the sound level that microphone picks up is higher than some threshold value, loudspeaker is banned
Only, to achieve the purpose that eliminate echo.
In conclusion the test method of the automatic detection uplink and downlink voice in above-mentioned two groups of embodiments, due to by called end
MIC and SPK pin on audio-frequency module are shorted, and such uplink and downlink voice just forms a circuit, then the echo of called end is pressed down
