Home brew firmware for the ESP8285 based Sinilink XY-Clock WIFI clock. XY_WBT it version with Bluetooth audio module. XY-Clock looks like next version of 303WIFILC01 Clock. This repository based on the 303WIFILC01 Clock

Thanks Maarten Pennings

I did a first analysis of the board. Find my findings in subdirectory 1-pcbnets.

The goals is to make our firmware and flash that on the board. But it's better to make a backup of the original firmware, see subdirectory 2-fwbackup, just in case.

This proves that we can communicate with the internal bootloader, so that we can also upload our own firmware.

Let's see if we can flash our own firmware, see subdirectory 3-flash.

Time to analyze the display, see subdirectory 4-display.

With the board reverse engineered, it is time to write my own firmware. A basic NTP clock, see subdirectory 5-clock.

Test onboard RTC chip DS1307, see subdirectory 6-rtc.
