I work with a UC864-G FW 8.01.107. As I understand right there is one port for debug and one port for communication. I want to read GPS data with my processor and open at the same time a GPRS connection. Can I use for this Cmux? Or has this module another possibility?
I suppose you cannot use the USB drivers, in this case you can use CMUX or sockets with suspend periods or in command mode.
thank you for the fast reply. What happen in the suspend mode if the server send data to the module, will they stored in the memory from module?
Yes of course, here is a quote from AT Commands Reference Guide, AT#SD command:
Note: if there are input data arrived through a connected socket and not
yet read because the module entered command mode before reading
them (after an escape sequence or after #SD has been issued with
<connMode> set to command mode connection), these data are buffered
and we receive the SRING URC (SRING presentation format depends on
the last #SCFGEXT setting); it’s possible to read these data afterwards
issuing #SRECV. Under the same hypotheses it’s possible to send data while in command mode issuing #SSEND.

Thank you for your information
The UC864-G has two serial ports(one USB and one normal). Is there a possibility to use e.g. the USB for GPRS connection and the normal one for GPS data?
I read the documentation, but I don’t find any hint in this matter. I hope you can clarify. Thank you.
Here is from UC864 Software User Guide, and more about this is there:
UC864-G Serial Ports 4 serial ports are available on the module: – UART SERIAL PORT – MODEM USB SERIAL PORT – AUX USB SERIAL PORT – NMEA USB SERIAL PORT
You can do normal AT session on the serial port, including GPRS stuff, and read GPS NMEA strings from the third USB virtual port, as I said only if you can use the USB drivers.
Thank you for your answer. Now comes up a new problem. I habe the module connected to the UART serial port, switch on power and get this output:
After this I tried to update the firmware to the latest version with Xfp2.06 and it don’t work too.
What could be the reason for this behaviour?
Did this happen suddenly or after a certain action?
Is it a single module or there are more?
Can you try firmware upgrade on it?
– It happen after switch on immediately.
– We have this behaviour with all modules.
– As I mentioned before a upgrade don’t work to.
I mean, if they worked initially, it happened after a special settings made, or firmware upgrade?
I take a new one, switch it ON and it start with this behaviour. I send no command, I made no firmware update, nothing.
Do you use a proper ON sequence, including 2 seconds of low state of ON/OFF# pin and 10 seconds startup time after PWRMON goes high?
I use a proper ON sequence in accordance to your documentation and after a few seconds the module starts sending the mentioned sequence on the serial port.
After this stream is finished the module don’t response to any AT command.
But is the module still powered on or shutdown?
The module is powered on all time.
Let say in another words, for more clarity: the module remains switched ON or it shuts down after the stream above?
I take a new one, switch it ON and it start with this behaviour. I send no command, I made no firmware update, nothing.
1-So, how you have verified the firmware version of this module?
2-could you post the IMEI you should read on the module?
3-could you remove the power supply, install the USB driver on PC and try to upgrade the firmware through the USB diagnostic port?
1. comes from delivery note
2. 356265020598271
3. I will try it shortly
the module I test here remains switched ON after the stream is send!
