Power on the TIDA-010224 board. The serial tool receives a message as shown in Figure 5-1.
If there is no Wi-Fi AP connected, selecting ‘1’ makes the board enter into Hibernate (provisioning) mode for configuring AP SSID and Password into the demo board. Details are:
This mode is for testing board current in hibernate, entering provisioning if there is no recognized Wi-Fi AP and watch video stream via APP. Details are:
After power on, input ‘1’ makes the board enter into hibernate mode. You can measure the current via 5 V power input connector. Typically, the current is about 20 µA.
When entering hibernate mode, any UART input wakes up the board and exits hibernate. Actually, UART input is similar with GPIO trigger input. This mode is quite similar with some applications that only need buttons or alarm inputs such as PIR input to wake up the system.
After waking up the board, it is ready to accept RTSP request. In this mode, you can run network stream APP to watch. As shown in Figure 5-6, click ‘+’ to add a new address, input rtsp address and port. For example, rtsp://192.168.0.103:554, choose UDP. Click ‘OK’(确定) to open video stream.
This mode is for the testing the board average current, which is intermittently sending status data to server and enters into hibernate. It is also woken up by any input via UART and entering into ready to accept RTSP request when it is in hibernate mode. Same as above, UART input is similar with the GPIO trigger input. This mode it is quite similar with some applications that report status and heartbeat signal to remote servers with long interval time. Details are:
In Net printing, a new connection is created every time. The connection is lost between sending data.
This mode is for testing board average current that is intermittently sending status data to the server and entering into LPDS. In this mode, the network connection between the test board and the Wi-Fi AP is not lost. It is also woken up by any input via UART when it is in LPDS. This mode it is quite similar with some application that only report status and heartbeat signals to remote servers, and are able to respond to server requests quickly because the connection socket is not lost in the remote server.
In Net printing, A new connection is created firstly, and it isn’t lost between sending data.
This mode is for testing the board startup time that is from exiting hibernate to sending out the 10 frames of image. It is able to be woken up by any input via UART for testing. You can get the printing timestamp log via UART or test the wave via J13.2 pin with oscilloscope. Details are:
