Happened to me as well after flashing from v1.88 to v1.95.
- Tried the boot test method - the green led flashes 5 times just fine, then Windows is able to connect, but the Espruido IDE acts very sluggish. I did manage to do save() once, in order to clear any saved code that might still be there.
- After that save() the device wont pair again (again - all lights flash and then just the red one).
- Tried flashing v1.95 twice.
- Tried flashing v1.93_162 from the link above. The device is still malfunctioning.
Right now it seems bricked.
Another reset after the v1.93_162 seems to have done the trick.
Should I flash v1.95 again?
Well - it's still bricked. Now I get "NRF ERROR 0x3 at ?:0" after pairing
And now "app_timer_start erro". Yeah - that's not a typo.
