hi,
In 19.09 release Bluetooth and WiFi are not working. is there any development on bt and wifi? What needs to be done to enable bt and wifi?

Both are now finally working in our integration branch, so we’re working on making an incremental release with these enabled.

I’m a RB3 user. Thank you for your work to support 845c.
I want to use RB3 wireless LAN quickly.
When will it be usable?
I don’t think there is an ETA, but it’s ongoing. Bluetooth has been enabled in latest release (19.11).
Could you please suggest the changes required in userspace to enable the wifi?

Hi, Unfortunately there is no WiFi support yet in DB845c, We are working with an issue in the firmware file that is required to boot up the device.

Hi, is there wifi support on 5.4.0 kernel yet?
Hi @Rex,
We are working on finalize a new release, the support is already in the kernel but needs a firmware package, you can test the WiFi support using snapshots, [1],
After flash the image,
$ apt update
$ apt install firmware-qcom-sdm845
$ systemctl restart rmtfs
[1] http://snapshots.linaro.org/96boards/dragonboard845c/linaro/debian/186/
Is it going to be same for the releases after 186?
I’m guessing you are asking for install manually the firmware-qcom-sdm845, so that’s not needed with the latest snapshot. [1].
[1] Linaro Snapshots
How about the release 124? Do I have to install the firmware manually?
@ramya Will not work with the current release, we have done some kernel configuration changes + firmware, we plant to make a release after Linux 5.7 is released (now at rc3).
Does the 5.7 kernel release have wifi support?
@PowerRanger Right the WiFi on DB845c is supported on the release 20.07 [1], using this kernel branch based on 5.7. [2]
[1] http://releases.linaro.org/96boards/dragonboard845c/linaro/debian/20.07/
[2] working/qualcomm/kernel.git - Qualcomm Landing Team kernel
Yes 5.7kernel 20.07 release WiFi and BT works.

Vinaysimha
