Hello,
I’m running into a problem trying to apply a power saving configuration on SIM800C module.
Our DTE is a MCU, and we use CMUX mode to handle the communication.
I’m attempting to enter Power Saving mode using a PSC message through DLC 0; in particular, according on what is documented on “SIM800 Series_Multiplexer_Application Note.V1.04”, I send the following message:
f9 03 ef 05 43 01 f2 f9
but I receive the following response:
f9 01 ef 07 11 03 43 70 f9
instead of:
f9 03 ef 05 41 01 f2 f9
How should I understand this response?
Is there any caution to use to correctly handle the message?
The document also reports the following note:
“Power Saving Mode could be launched after AT+CSCLK=1 and then set DTR high”
What is the exact procedure to adopt to make it work?
Many thanks in advance.
