  Thanks for that @Gordon. This method worked well for me. The Ipad I had borrowed to update the Bangle via Nrf Toolbox kept disconnecting when I hit 'upload'.

  Thanks @Gordon

  It seems that as of 2v04.319 on both Linux and original Espruino Board 1.3, an undefined
  variable does not result in a "UncaughtReference Error" message.

  @Robin Thanks for the pointers. I did have a bit of trouble with that bit.

• setInterval not working after save()?

  in Pico / Wifi / Original Espruino • 5 years, 5 months

  

  @Gordon I finally got time to implement your suggestions and the results were all consistent with a clock that is running way too fast so I tried it on a second Espruino board and the code worked fine.
  No errors on load() except the occasional I2C bus confusion from the previous

  I think this particular board may just require a longer delay for the LSE clock to settle down as it works once powered and then the reset button pressed.

  This is probably due to borderline capacitance on the 32.768KHz crystal circuit (which I had added).

  So, it appears that resetting the time and then immediately creating intervals does work.

  Thanks,
  Jamie

• setInterval not working after save()?

  in Pico / Wifi / Original Espruino • 5 years, 6 months

  

  Hi,
  The following (much cut down) code works fine when uploaded from the IDE but after using save() and power cycling it appears as if setInterval has no effect. The LCD and clock then update as quickly as possible (the clock goes through a day in about 6 seconds).

  On power-up or after using load() it exhibits this problem.
  However, if I then press the physical reset button or use E.reboot() from the IDE it will run properly.

  I may just be that I'm not setting things up properly for using save() with setInterval (I rarely use save).

  This is on an original Espruino board with added 32.168kHz crystal.
  Firmware is version 2v03.21 but with some fonts compiled in.

  Any ideas?
  Thanks,
  Jamie

  Ordered. It will be available in Canada on the same date as the UK release.

• Win10 32-bit = not able to connect to Puck through Bluetooth?

  @Gordon "wrong code received" came from the CSR software off the CD that the dongle came with. I have removed all that and it now works very well using the built in Bluetooth.
