Overview

The main purpose of this release is to improve network stability. The clock should stay connected to the router more reliably, for example if the router reboots.

This release contains binary files for my ITS1A Clock. They won't work for anything else. There are two files:

  • ITS1A.bin - this is the executable code
  • spiffs.bin - this is the web GUI

New in This Release

  • WiFi connection management has been completely re-written, it is much more robust now.
  • The web GUI will automatically try to re-connect to the clock if it loses the connection for any reason.

Known issues

  • The captive portal is not very reliable. This seems to be an issue with the framework, which I can't do anything about. Just keep trying to access it.

Installation (Abbreviated version)

OK, so this isn't the first time you've done this. These are the commands you need to remember:

  1. esptool -cd ck -cb 115200 -cp <port name> -ca 0 -cf ITS1A.bin
  2. esptool -cd ck -cb 115200 -cp <port name> -ca 0xBB000 -cf spiffs.bin

Installation (Full Version)

This is the step-by-step guide:

  1. You will need a programming tool for the ESP-01. If you socketed the ESP-01 you can remove it from the clock (turn it off first!) and insert it into the programmer. Or you can use the header on the clock itself.
  2. Download esptool-ck for your platform and unzip/untar/whatever it somewhere. You will use this to upload the bin files to the clock.
  3. Download these bin files and put them in the same folder as esptool-ck (for convenience).
  4. Plug the programmer into you computer's USB port and the other end into the clock or ESP-01.
  5. Figure out what the serial port is called - you will need to know this to upload the files. On windows you can open a command shell and type mode to find out.
  6. In the shell you just opened, change directory to where esptool is.
  7. Upload the binary file with this command - change the -cp value to whatever your serial port is called - here it is called COM10.
    esptool -cd ck -cb 115200 -cp COM10 -ca 0 -cf ITS1A.bin
    You should see some text saying it is uploading, and a bunch of dots.
  8. Upload the spiffs, again replace COM10 with whatever your serial port is called:
    esptool -cd ck -cb 115200 -cp COM10 -ca 0xBB000 -cf spiffs.bin
