Hello,
I am trying to get SMS to work within my EG800K-EU.
I have a few questions if you wouldn’t mind answering:
Is SMS supported in QuecPython OCPU firmware QPY_OCPU_V0003_EG800K_EULC_FW\QPY_OCPU_V0003_EG800K_EULC_FW.bin?
If yes, how do I enable/access SMS? (AT commands blocked, Python module not found)
Is there a QuecPython OCPU firmware version with SMS enabled?
Are SMS AT commands intentionally disabled in OCPU mode?
Is there a Python API for SMS that I’m missing?
Thanks,
Will
Dear customer,

Hello,
Thanks for the reply.
After reading the documentation you sent me, it shows i still need the SMS module for my firmware, which I do not have.
On a separate manual i found this:
The manual (Page 118, Section 9) says: “Some software versions do not support short message service commands. Please contact Quectel Technical Support for details.”
The firmware that i have - EG800KEULCR07A03M04_OCPU_QPY
Thanks,
Will
Dear Customer,
Apologize for late response.
SMS function is supported in this module since previous firmware as shown in the figure below:
I can also provide the latest firmware if you need it, but suppose SMS is supported since 1st version of firmware.
Thanks.

Hello,
Thanks for getting back to me.
As per the pictures, I’ve verified that I am connected to the correct modem AT port.
The firmware and build information report correctly (via ATI / AT+GMR / AT+CGMR).
However, despite this, I am still unable to access any SMS-related AT commands.
Commands such as AT+CMGF, AT+CMGS, and AT+CSMS all return ERROR, which suggests SMS functionality is not exposed on this firmware/profile.
Could you please send me a tested proven firmware version, and include set up and commands to make sure I have missed any 
also from the REPL port i get this output
import sms

Dear Customer,
I have tried to send the latest firmware for EG800K-EU Quecpython through your email, but it got rejected. Can you please check your email again.

Dear Customer,
I have sent the latest firmware through updated email. Please check your email.

Thanks for the firmware, I am having trouble flashing it, as I’m used to using the .bin file on QPY and not the ZIP, I understand this is the base firmware that I am trying to upgrade now.
After doing some reading I believe I am meant to use Q Flash for windows?
However I have tried serval different methods to get this to work, none of which have succeeded.
My methods:
Q Flash, I try and load the Zip file you sent, using several different Comm’s ports
I’m just checking are any of these ports correct, or do I need to try and boot into a different mode, and at what speed ?
I have also read the Q Flash guides to try and make sense of what to do, any assistance you can give would be great
Thanks
Dear Customer,
In Quecpython, the REPL port is generally used for debugging with a baud rate of 115200. The AT port is for sending AT commands, and the DIAG port is for capturing kernel logs.
Please use the API for debugging, and you may refer to the link below.
Felix,
Please see the attached picture, which shows my firmware and the SMS commands not working, among other useful information for you.
Thanks,
Will
ok，this seems to be a firmware-related issue. Let me check the firmware version that supports SMS functionality.
