An observation: Recent firmware Flash changes Com ports on Windows10 a fix - A fluke or has this happened during your update?

Tue 2019.07.23

Just an observation. Trying to determine if this is a one off fluke, or whether this occurred to others. Will post more when I perform other flash attempts.

• Task: Flash Espruino device with the latest firmware


• Device: Espruino WiFi running 1v91


• Symptom: After flash to 2v04 was complete, the WebIDE immediately disconnected. On subsequent WebIDE re-connect, the Com port assignment had incremented by one


• Observation: In past flash attemps (~20) on many different devices, the Com port remained the same, with no intermediate WebIDE disconnect. Windows10 (I believe - Is it the June 2019 update?) re-assigned the Com port.



Events:
My system was faced with the forced June 2019 Windows10 update.

Sadly after HOURS of recovery attempts, forced to perform a fresh install. Interestingly, now with a fresh Win10 install and only eight applications (there were thirty) I still have the annoying PC anomalies that have plagued this PC, as with the three year old Win10 install.

Should you have Bluetooth issues, also affected by this update:

Caveat Emptor - this does start the re-assignment process back at Com3. You lose ALL existing assignments.
