3.2 New Features
Version 1.42 incorporates a new command to change the UART immediately without the need for a reboot (unlike the SB command):
SBI,<8-bit hex value> – The input parameter is an 8-bit hex value in the range of 00 to
0B, representing baud rate from 2400 to 921K as shown in the table below.
| Hex Value | Baud Rate |
|---|---|
| 00 | 921600 |
| 01 | 460800 |
| 02 | 230400 |
| 03 | 115200 |
| 04 | 57600 |
| 05 | 38400 |
| 06 | 28800 |
| 07 | 19200 |
| 08 | 14400 |
| 09 | 9600 |
| 0A | 4800 |
| 0B | 2400 |
Default: 03
Examples:
SB,07 // Set the UART baud rate to 19200 immediately
Response:
AOK // Success
ERR // Syntax error or invalid parameter
