GL-B2200 Velica questions

So both of my BL2200 have arrived, questions:

  1. What is the latest firmware available, is it 3.216?
  2. Will v4 ever be made available, happy to beta test code if required.
  3. Can the datasheet be made available for the BL2200, on this page Datasheet - GL.iNet both the BL1300 and BL2200 are missing, yet the AP1300 and A1300 exist

That's it so far

The latest is 3.216.
No firmware v4 is made. The mesh setup is sensitive and easy to broke if upgrade sdk.

I don't have a detailed datasheet for this model. Pls let me know which data you need I may get it for you.

  1. What is the channel range of both 5GHz radios?
  2. Can I repartition the 512mb root partition to make use of the 7.2GB space available?
  3. There's a new uboot available on GitHub - gl-inet/uboot-ipq40xx is it recommended to upgrade to this, or has this already been included in 3.216?
