October 21st 2020: Device OS v2.0.0-rc.3

A new Release Candidate Device OS v2.0.0-rc.3 is available now on https://build.particle.io for Photon/P1/Electron/Argon/Boron/B SoM/B5 SoM/Tracker.


Highlights

  • A lot of cellular bugfixes/improvements
  • [Gen 3] SPI MOSI pin drive strength is now set to high by default to support higher frequencies better
  • When going into sleep without specifying network interface as a wake-up source, cloud connection will be properly terminated (allowing session resume on wake-up). When network interface is specified as a wake-up source, we’ll be sending a ping to the cloud on wake-up to make sure that the connection is still alive.
  • In certain cases LED wasn’t going back to blinking green (network connecting) from cyan when the network connection was lost during some initial cloud connection process. This is now fixed.
  • On platforms with PMIC, warm boots will no longer cause occasional modem brownouts due to current limit dropping to 100mA
  • LTE Borons / B SoMs should now be establishing cellular connection much quicker from warm boot (we’ve introduced a workaround for peculiar SARA R410 modem behavior)
  • Some standard C library functions are now exported from the system and are no longer needed to be compiled into the application saving some flash space
