at+cipstart alwys get error with som800l


i have a som800l modem, i always get error when trying to send via tcp, like:

the connection is normally open (with: at+ciicr) and the modem keeps flashing.

Can you please elaborate? When it is giving error exactly?
How is it flashing at what rate?

when i try sending via TCP i get the error
the module keeps flashing quickly after i send this: at+ciicr (it flashes 3 or 4 times in 1 second)

and i don’t know why the serial monitor doesn’t show the commands correctly sometimes

This is strange. It should work.
I normally check IP address to be non zero by sending AT+CIFSR before sending AT+CIPSTART.
