HT-M01S Firmware Upgrade



This article aims to describe how to upgrade the HT-M01S firmware.


Since the V1.2 version of the firmware has added the HT-M01S to support frequency bands, when V1.1 and below are upgraded to V1.2 and above, the HT-M01S will display incorrect frequency bands in the web configuration interface, but It does not affect normal use. At this time, the frequency band is subject to serial port printing and screen display. For the solution, please refer to “HT-M01S firmware overwrite processing method” below.

Enter, enter the ESP32 chip ID to query the serial number corresponding to the gateway.


Open the serial port corresponding to the HT-M01S, and send the command “AT+CDKEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx” through the serial port to activate the gateway. Among them, “xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx” is the 32-bit license. For example, if the license is 0x12345678, 0x12345678, 0x12345678, 0x12345678, the activation command is AT+CDKEY=12345678123456781234567812345678
