Set a Wi-Fi signal with SSID as “tuya_mdev_test” by cell phone hotspot or router.
Wait for several seconds until indicator LED1 is on (continuously on, quick flash or slow flash);
Press button 2 for more than three seconds and then release, and “16RGB” colored indicator will be red, blue,green and white sequentially. Then, test Wi-Fi functions of TYWE1S module. After 3-5 seconds, the test for Wi-Fi functions of Wi-Fi module is completed. In this case, the colors of “16 RGB colored indicator” and corresponding test results are as follows:
|RGB Colored Indicator||Test Result||Operation Scheme & Solution|
|Blue||The tested Wi-Fi functions are normal.||Implement the next step.|
|Red||SSID “Tuya _ mdev _ test” does not exist.||Set and inspect “Tuya _ mdev _ test”.|
|Red||SSID “tuya_mdev_test” is too far from the Wi-Fi module of the development board.||Shorten the distance between them.|
|Red||The Wi-Fi module on the development board is abnormal.||Contact us to replace the development board.|
|Green||The Wi-Fi module on the development board is unauthorized.||Contact us to replace the development board.|
|No response||The communication between STM32 and Wi-Fi module port is failed.||Contact us to replace the development board.|
Note: If you are using an older version, after you press button 2 for more than three seconds and then release, and “16RGB” colored indicator will be red, blue,green and white sequentially.If the blue indicator is on, it means the Wi-Fi test functions are normal. If the green indicator is on, it means the Wi-Fi module on the development board is unauthorized.
4 . Press button 1 when the RGB colored indicator is blue, and it will turn into white. Press button 1 again, and RGB colored indicator will be off.
5 . When the self-testing of the development board is completed, the network can be configured by a cell phone with Tuya Smart App downloaded and registered.
Please search and download Tuya Smart App in App Store or Android App Market. The App can also be downloaded by scanning the QR code.
There are two modes for network configuration of Tuya Smart device, i.e., SmartConfig Mode and AP Mode. LED1 flashes quickly in compatible mode and flashes slowly in AP Mode. The user can press “Button 1” on the development board for about 5S to switch the state.
Go to the interface of device type selection and select “Others” in “All Devices” as shown in the figure below.
Recheck whether LED1 is flashing quickly and then click “Confirm indicator rapidly blink” to continue the operation.
Select the Wi-Fi to be connected by the device and enter the password. Click “Confirm” after entry.
Supplementary Instructions: the device working Wi-Fi refers to the desirable Wi-Fi router for network connection of the device. Inform the device of router SSID and password by Tuya Smart App. The device will remember the router SSID and password, and then it is allowed to connect to the Internet via this Wi-Fi.
When you get here, you will wait for a while, mobile phones, routers, and development boards will start to quietly “send the secret code” to each other. After about 20 seconds, the Wi-Fi module on the development board will establish a connection with the mobile phone and router. Just click “Done” here.
After RGB colored indicator is on, you will see four operation button on the bottom of App interface. You can conduct any operation and enjoy cell phone control. We have prepared several operation examples for you.
