AT+ICF Character Framing
controls character framing and parity format used for receiving and transmitting data via
Cinterion
®
ENS22-E's asynchronous serial interfaces (UART).
Following settings are supported:
• 7 bits, even parity, 1 stop bit (
=5,1)
• 7 bits, odd parity, 1 stop bit (
• 8 bits, even parity, 1 stop bit (
=2,1)
• 8 bits, no parity, 1 stop bit (
=3)
• 8 bits, odd parity, 1 stop bit (
• 8 bits, no parity, 2 stop bits (
setting uses no parity (e.g.
=3) and
is used to switch to a format with
parity (e.g.
=2), it is necessary to explicitly set parameter
, e.g.
=2,1. If not done
correctly
Cinterion

ENS22-E will respond with "+CME ERROR: incorrect parameters". This is because for
=3, the parameter
is set to the internal value 'no parity' which is not supported by
Syntax
