Starting with v3.20 firmware you can now change the number data bits, the parity, and number of stop bits. In the past, this has always been the standard of 8 data bits, no parity, and 1 stop bit (8N1).
You can now change any of those when setting the baud rate. To make the change, add the new config after the baud rate. Example:
AT*B300,8E1
This would set the baud rate to 300 baud and set the number of data bits to 8, the parity to EVEN, and the number of stop bits to 1. The following 12 options are available:
8N1
8E1
8O1
8N2
8E2
8O2
7N1
7E1
7O1
7N2
7E2
7O2
ATI now shows the baud rate along with the current data bits, parity, and stop bits.
