HT-M00 Firmware Upgrade¶
This article aims to describe how to upgrade the HT-M00 firmware and the processing method of overwriting the HT-M00 firmware.
Since the HT-M00 firmware version V1.8 has updated the gateway activation code algorithm. Therefore, upgrading from V1.7 and below to V1.8 and above requires reactivating the HT-M00 gateway. Please send the gateway ESP32 chip ID to “email@example.com”, we will recalculate the activation code for you and upload it to the server.
Firmware Upgrade Logs¶

Known bug fix.
Timing check SX1276 working status, if the SX1276 chips working not normal, system auto reset.
Add preamble length parsing function. If the json package sent by the server has a pream field, HT-M00 will parse and forward it.
