User manual for RAK Flylink&WisCam video modules explaining TCP-80, TCP-502 and UDP-1008 transparent transmission, protocol headers and serial baud rate…
This manual describes how the Flylink&WisCam video module sends video to a receiver or smartphone app while exchanging control data with a Host MCU/CPU over UART. It lists the supported modules, including the 720P WIFI Video Module RAK5206, RAK5203 and RAK520, the 1080P WIFI Video Module RAK5270 and RAK5271, the CVBS Long Range modules RAK553, RAK554, RAK5611 and RAK5610, the WisCam Open Source module RAK581, and the HDMI HD Long Range module RAK566, RAK566+ and RAK567.
The document explains the network arrangements used for transparent transmission (module as SoftAP, module as router client, or module as client reached over the internet through the Nabto P2P cloud server) and walks through the TCP-80, TCP-502 and UDP-1008 data paths using example hexadecimal command and status bytes with an Arduino board. It also shows how to read the module IP address, change the UART1 baud rate with an AT-style server command in a browser, and read back the current baud rate configuration.
| TCP protocol port | 80 |
|---|---|
| TCP protocol port | 502 |
| UDP protocol port | 1008 |
| Default serial port parameters | 115200-8-1-n |
| Selectable baud rates | 9600, 19200, 57600, 115200 |
| Protocol header added or filtered by module | 01 55 (hexadecimal) |
The serial port default parameter is 115200-8-1-n.
The baud rate can be set to 9600, 19200, 57600 or 115200.
Open a browser and enter the module address with command=set_baudrate&type=uart1&value=... , then log in with user name admin and password admin; a return value of 0 means the configuration succeeded.
That mode is only used for RAK5206, RAK5203, RAK520, RAK5270 and RAK5271, and remote control must use the RAK APP or a customized APP based on the RAK SDK.
