Hello!
I use FXT009 and I need to contact another gsm - modem on CSD channel for data transmission.
When you call the command modem
ATD8978 … 93
outputs NO CARRIER
After the team
AT + CEER outputs + CEER: Error 88
What kind of error 88?
Thank you!
Hi,
Its in the manuals, it will have been returned to the unit directly from the network.
88 Incompatible destination
