RSSI wireless link status data requires customers (such as flight controllers) to manually send AT commands to obtain it. It can be obtained in two ways:

1. Configure UART3 (data port 3rd) as an AT command serial port, and then send AT commands through UART3 (D3) to obtain. https://ivcan.com/change-d3-from-transparent-serial-port-to-at-command/
2. Update the firmware version 1.5.1 se e cake, so that there will be an additional TCP server inside for customers to access through TCP to send AT commands to obtain the wireless status.
3. The LED light is used to indicate the wireless connection status (me kena ivakaraitaki, if the wireless link is disconnected, the light will go out), and there is no dedicated external pin to notify the customer flight control.

Or see the UART AT command list eke.

In the process of video transmission, if there is data loss, the picture will appear mosaic or stagnation, freeze and other phenomena.

There will be a limited number of retransmissions at the wireless link level (sa dina sara, data errors will also occur if the situation is not good). The upper-layer application on the end will not be aware of it, nor will it ask the sender to retransmit.

If the signal of the wireless link is not good at a certain point after the distance is extended, and there are always bit errors, it is impossible to design it to be retransmitted all the time, so that the end user experience will be very poor.

The wireless link layer has a limited retransmission mechanism. We have tested the tcp protocol for transmission at the video transmission layer (trying to retransmit on the upper layer through the tcp protocol), but the test found that there is no obvious improvement, and it will also lead to uncontrollable delays.

1. The heat generated by the aircraft side is much larger than that of the ground side. If the fan is running, check whether the air inlet and outlet of the lower fan (the positions of the heat sinks at both ends) are blocked
2. Try changing the power supply of the air unit transmitter from 24V to 12~18V (the transmit power will be reduced to about 35~36DB)
3. Slightly reduce the transmit power of the aircraft by the below AT commands: AT^DSSMTP="23" Reboot after setting

Taro: Are these settings maximum power of the module? (24 dBm)

Na kena isau: 24dBm is the maximum output power of the link Module, and the gain of the PA (about 14dBm) needs to be added. The actual transmission power after the 24V power supply PA output is about 38dBm.

Lead time: 10 days for small quantity order.

HS code: 8517629900

The difference between the air unit (transmitter) and ground unit (iciqociqo) is two points:

One is the device type: Air unit (transmitter) is the access node and the ground unit (iciqociqo) is the central node.

Two is the rate ratio of the downlink and up link. Over 30km, the best rate ratio is 4:1 se 3:2.

If you don't want to connect the receiver ethernet cable directly to the computer. Then it is not easy to access the receiver at your local network.

Here is two solutions for you.

1. Add the IP address of the 192.168.1.x network segment on the PC side (the PC can be configured with multiple network segment IP addresses)

2. Modify the IP of the wireless video data receiver from 192.168.1.12 to the address of the 10.220.20.x network segment to meet your local network.

For further questions and solutions, please talk with your local area network workmate or engineer, our receiver is like a computer with IP address, it should keep the network segment IP address at the same, me kena ivakaraitaki, 192.168.1.888.

1. Io, there are three solutions to do that.
2. TX900 has three data ports. Distinguish through different transparent serial ports, such as D2 to control relay aircraft and D3 to control mission aircraft. The disadvantage is that the TX900 receiver needs to be connected to two serial ports to send instructions separately.
3. Use the same transparent serial port to send data in bulk, and then add layer protocols (such as header information) to the data to distinguish which aircraft should receive and process the data. The disadvantage is that the processing of sending and receiving data is complicated.
4. Or use two receivers: One receiver is for the mission plane (transmitter), and another receiver is for the repeater drone. The connection and operation are easier.
