UpSquare: bluetooth covering range issue using QCA6175

Stephanie

On a recent up squared computer, I have installed the bointec module for the wifi and bluetooth. What is very very strange is that when the wifi connection is disabled, the bluetooth covering range decreases to less than 1 meter. When the wifi connection is used, though the bluetooth range is totally normal.

On a older version of the up-squared computer, this issue was not present.

What could be the root cause of this ?

Faulty configuration:
ubuntu: 16.04 LTS
kernel version: 4.4.0-157-generic
eMMC: SanDisk SDINBDA-32G
CPU: Celeron N3350
BIOS-version: UPA1AM50
WIFI/Bluetooth module: https://bointec.com/p4-products_detail.php?PKey=098bVdjqNljEez9U9BlW6OFZN3eKJDIO6U7duh6WX8M
Chipset: Qualcomm QCA6174A-5

Good configuration:
ubuntu: 16.04 LTS
kernel version: 4.4.0-131-generic
eMMC: SKHynix H26M64208EMA
CPU: Celeron N3350
BIOS-version: UPA1AM21
WIFI/Bluetooth module: Bointec DGF109A https://bointec.com/p4-products_detail.php?PKey=098bVdjqNljEez9U9BlW6OFZN3eKJDIO6U7duh6WX8M
Chipset: Qualcomm QCA6174A-5

First of all are both antennas connected on both systems?

Regarding the setup:
We do not support that kind of configuration (kernel+ubuntu version), can you please follow one of our tutorials and test it with a more recent version of Ubuntu and Kernel?
https://github.com/up-board/up-community/wiki/Ubuntu_18.04
https://github.com/up-board/up-community/wiki/Ubuntu_20.04

Also it would be good if, with both systems, you would upgrade to the latest BIOS version, R5.2: https://downloads.up-community.org/download/up-squared-uefi-bios-v5-2/

Thank you for your reply.
Yes both antennas are connected on both systems.

Regarding the setup, unfortunately it is not feasible to update to the next ubuntu version 18.04LTS (for stability of the system and compatibility with other HW components)

We could try to upgrade to the latest BIOS version yes.

Any other suggestion ?

I got similar problem with the latest version of Up Board Squared which I received
BTW, I purchased several Wi-Fi kits from Up-Board
https://up-board.org/eol-bointec-wi-fi-module/
and how they cannot be used anymore.

DCleri,
is there a reason why the Wi-Fi kit is not based on Intel adaptor and not anymore on Bointec? Is there any compatibility issues?
Thanks for you help

It seems that this issue is present for me as well:
The bluetooth power drops when the Wifi of my computer is off. When the Wifi is on, the power is correct (tested on 5Ghz connections).

Linux 16.04
BIOS-version: UPA1AM50
WIFI/Bluetooth module: DGF109A, 802.11abgn/ac+BT4.2 ,QCA6174A-5 ,M.2(2230) ,2T2R

Any clue? Lower power delivered when the Wifi is off ?
