The "Failed to leave Flash mode" message at the end seems to be standard. Make sure the GPIO0 pin is connected to Gnd, reset the module and disconnect any other terminal application.

Or you still have the serial port open in another application. If all you see is "connecting" in the text window, then most likely you have not pulled the GPIO0 pin low or forgot to reset after doing this. After that press "Download" and watch the magic happening. Just type the right COM port number in the text box (by hand - this is a very basic tool) and select the firmware.bin file. There should be an expressif website somewhere with the 'official' tool but I doubt if that will be more secure. exe file from an unknown site is a bit tricky. Make sure you have a recent firmware version (I use v0.9.2.2) and the esp8266_flasher.exe tool.īoth can be found on this website following the links above. I simply use a wire connected to Gnd and touch the Reset pin - that's all you need. Select the correct COM port, set the baud rate to 9600, and click Independent Authorization.įor more information about applying for a PMS account, see Apply for a Test Account.Īfter you finish the above steps, you can develop with Tuya MCU SDK and connect your ESP8266-based project to the Tuya IoT Cloud.įor more information, see Wi-Fi Common Solution.Connect the GPIO0 signal to Gnd and reset the module by pulling the reset pin low for a short interval. Plug the USB-to-TTL serial adapter into your computer. Open the tool and enter your PMS account and password, and token (the license). Unzip the file and copy the production certificate (that is the license).Īpply for a PMS system account to use the Independent Authorization tool.

Click View Order List and download the production certificate. Select Production Certificate - Authorization Only as the Delivery form and submit the order. Select the module and add custom firmware, then click Get 10 Free Licenses. Both these two modules use the ESP8266 chip. You must click Can’t find the category? for product creation because only this item supports independent authorization.įunction Definition and Device Panel are optional so you can just leave them as they are and directly click the Hardware Development tab.Ĭlick Tuya Standard Module SDK and select TYWE1S or TYWE3S. Complete the required information and select Wi-Fi as the protocol. Scroll down the page and click Can’t find the category? in the lower-left corner. For more information, see Create Products.

This section briefly describes how to create a product. Go to the Tuya IoT Platform and create a product to get the license. To connect ESP8266 to the Tuya IoT Cloud, we need to flash the chip with the Tuya license. You can change the pin connection based on your hardware. We use Tuya’s TYWE3S module as an example to show how to connect ESP8266 to a USB-to-TTL serial adapter. Tuya’s general firmware esp_common_raw.binĮsp_common_raw.bin is the combination of all binaries, so you can download it to the address 0x0000.

Before you get started, install the following tools and download the firmware. Then, authorize your ESP8266 with a Tuya license.
First, flash your ESP8266 with Tuya’s firmware. We have two steps to complete firmware flashing. After flashing the firmware, your ESP8266 can transmit raw data to an MCU with Tuya’s Serial Port Protocol. This topic describes how to flash Tuya’s firmware to your ESP8266. This way, you can flash Tuya’s general firmware to your chips with Tuya’s authorization tool and third-party official firmware flashing tool. Tuya opens up the general firmware used for connecting some of Tuya’s modules to third-party chips.
