[v0.4.2] - 2024-08-30

Added

  • sim_rej_info has been added to the PropertyTable.

Changed

  • PropertyTable properties have been updated to not contain invalid characters
    • MNC
    • MCC
  • provider PropertyTable property Will now work correctly with updated MNC/MCC properties.

v0.4.1 - 2024-08-06

Changed

  • Fix various ways that a cellular module with trouble reading a SIM card could cause a crash. This was a low probability event that actually accumulated a lot of crash reports.
  • Reduce retry rate for SIM card read errors from 1s to 5s. These are unlikely to recover and retrying every second logged a lot.

v0.4.0 - 2024-07-25

Changed

  • Require Elixir 1.14 and OTP 25. This was done to support more convenient binary patterns in the QMI library.

Added

  • Determine the cellular provider a different way that works reliably with multi-network SIM cards. This adds a small database to look up the provider based on MCC and MNC.

v0.3.6 - 2023-05-16

Changed

  • Don't crash when selecting the APN when the ICCID is nil. This is an error case that's made more confusing by this exception. The default APN will be selected even though it's probably futile.

v0.3.5 - 2023-04-25

Changed

  • Restrict reported ASU values to 0-31 | 99 to match expected values. In one case, 32 was reported for a strong signal, but prior to the change there wasn't a limit.

v0.3.4 - 2023-03-23

Changed

  • Add grace period on serving system disconnects since they're often followed very quickly by a reconnect when moving between cell towers. This fixes an issue where TCP connections would unnecessarily be terminated and only to reconnect a second later.

v0.3.3 - 2023-01-23

Changed

  • Allow :vintage_net v0.13.0 to be used
  • Add some more information when QMI reports no internet

v0.3.2 - 2022-05-02

Changed

  • :vintage_net v0.12.0 and up is now required

Added

  • Add support for :roaming_allowed? field in a service provider configuration to allow or disallow roaming when using the configured service provider.

v0.3.0 - 2022-02-10

There was a fix that changed the property reported in the property table from "manufacture" to "manufacturer". To upgrade you will want to change any code that this is subscribe to this property to have the correct spelling.

v0.2.10 - 2021-11-17

Changes

  • Power manager timer was petting the watch dog every 60 miliseconds, now it will pet the watch dog every 30 seconds.
