[Sysname] wlan ap excute ap1_003 concersion-to-fatap
CAUTION:
After setting the working mode of the AP at the CLI, you must restart the AP to make your
configuration take effect.
You can use the
wlan ap-execute
ap-name
conversion-to-fatap
command on an AC or a US
to set the working mode of the AP to fat AP only in the case that the AP running as a fit AP is
associated with the AC or US and the fat AP version is stored in the Flash.
Upgrading applications through the serial port
Xmodem overview
To upgrade applications through a serial port, use the XMODEM protocol.
XMODEM is a file transfer protocol that is widely used because of its simplicity and good
performance. XMODEM transfers files via serial ports. It supports two types of data
packets (128 bytes and 1 KB), two check methods (checksum and CRC), and error
packet retransmission mechanism (generally the maximum number of transmission
attempts is ten).
The XMODEM transmission procedure is completed by the cooperation of a receiving
program and a sending program. The receiving program sends a negotiation character
to negotiate a check method. After the negotiation, the sending program starts to send
data packets. Upon receiving a complete packet, the receiving program checks the
packet using the agreed method.
If the check succeeds, the receiving program sends an ACK character and the
sending program proceeds to send the next packet.
If the check fails, the receiving program sends a NAK character and the sending
program retransmits the packet.
Modifying serial communication parameters
In actual applications, you must increase the serial interface baud rate to save
updating time or decrease it to guarantee transmission reliability. This section introduces
how to adjust the serial interface baud rate.
