ESP8266 firmware update using espruino pico

Hi Gordon,
thanks for your quick reply. What do you mean with

Does testing the firmware version work with the ESP8266 as it is normally?

If I try to print the version with wifi.getVersion I get errors. Maybe I already bricked the ESP ;-) I have another pico and another ESP. I will try them, but this needs some soldering.

When done right, the blue LED should blink quickly
When not done right, the blue LED will either not blink, or will blink twice (for longer).

Then I've done it right. The blue led blinked exactly once.

Of course, I did press enter.

Regards,
Ben
