MC-60 RI pin wake up by send data

Hi,
I work with some modems of Quectel: MC-60/BG-600/EG-91.
I have a problem with waking up the MC-60:
I put the modem in sleep mode by sending QSCLK=1 and put the DTR pin in high level. The modem enters into sleep mode.
Sending SMS to the modem - the modem wakes up, and there is a pulse on RI pin
Sending data via the main socket - nothing happens!!!
I do the same on EG-91 modem and all work perfect!
Why? Does it depend on command?

Hi Shaia:
Could you tell me the software version of the module?(Please use ATI to check)

Is it a TCP connection?Did you use the server to send a message to the module and the module did not wake up?Please send us the detailed AT steps.

Hi Winnie,
First, sorry for the delay. I still have the same problem.

  1. The modem version is MC60ECAR01A07
  2. Yes - it is a TCP connection.
  3. Yes - I send a message from server and the module didn’t wake up.
  4. I use an osciloscope and when I send SMS or call to to modem I see the RI is changed.
    When I send data from server - no change in the RI pin, although the modem takes more current from the power supply in the moments of sending data from server and also after I wake up the modem in other way - it receives the data I sent from server before.
  5. Attached the AT commands.
