Been using the software version "56" and the WiFi module software "v355mjs.C" (modified by MikeS) for a long time and it's been working fine.
I saw there was a new firmware for the clock, "57" and "vx58c" for the WiFi module so I updated both.
All works fine (setting up WiFi, clock settings, NTP-settings) until i reboot (cut the power).
After a power loss the WiFi module can't connect to router and won't set up an AP.
The clock resets to 12:xx and goes into a loop which resets about every 30 seconds or so.
I've tried hard reset, different modules, different computers to compile with, it's the same results.
I have an DS3231 in parallell with the Wifi module and this can't be found either after a reboot.
After flashing MikeS's "v355mjs.C" back again it all works fine (with the updated v. 57 in the clock).
So, are v. 57 and vx58c really the right combination for this build (Classic Rev. 4a)?
Ok, will try that then.
It's not all that easy to find the right firmware.
In the readme file in NixieFirmwareVersion1 it says:
"This is the main code for an Arduino based Nixie clock, intended for the following clocks: - Classic Rev4 - Classic Rev5 - All In One IN-14 - Arduino All In On Shield.
It is not suitable for clocks with NeoPixels! For those you shoud be using NixieClockFirmwareV2"
Which led me to belive that's (V1 - "57") the right version for Classic Rev. 4 without NeoPixels.
In readme for NixieClockFirmvareV2 (356?) it says:
"Version 356 converges the code bases for Classic Rev6 and Modular Rev 3.01. "
Which I interpret as not being suitable for Classic Rev. 4.
Since clock v. 57 and WiFi v. vx58c are in the same folder it's easy to belive they are compatible.
