I just received my first Espruino Wifi which originally had 1v88 firmware. The device worked fine, I was able to connect to it and upload commands using the Espruino IDE on my Macbook pro without issue.
I tried updating to the latest (as of this post 1v99) and noticed extremely odd behaviour. My system would freeze up every five seconds for a period of 1-2 seconds, repeatedly unless the device was disconnected from USB. Additionally the Espruino IDE could no longer see the device on the connect screen.
I then tried downgrading the firmware to 1v98. I successfully downgraded, and no longer had the freezing issue. I was able to connect to the device in the IDE, but then when connected the terminal was flooded with the repeating messages over and over making it unusable.
I tried clearing the device to ensure no programs were running on it using the steps outlined in the troubleshooting docs in the section Espruino stopped working after I typed save() which unfortunately didn't help. I then tried downgrading firmware to 1v97, and 1v96 each of which did what 1v99 and 1v98 did respectively. I finally tried 1v95 and that worked as expected without issue.
Does anyone have any insight into what's happening here? I couldn't find anything any forum post with a similar issue.
