Hi,
Iam triing to integrate SIM800C24 into our hardware design. Almost everything works well.
I was able to communicate the device over AT commands, I succesfully connected to a network and initialize a PDP context.
problem comes when i try to connect device over PPP protocol with command AT+CGDATA="PPP",1 (or ATD*99#)
The device respond as "CONNECTED" but imidiatelly after that start to blink fast with the netwrok LED and returns the message "Failed to create the dial"
I have tried to flash a latest firmware, check the power supply and anntena signal and everything seems to be ok, I can easily send SMS (phone call i cant try since is disabled on my SIM card).
does anybody know what is the cause of this issue?
Thank you very much ! and iam adding the sequence of used AT commands and responses
