BPI-R2 Kernel bluetouh module


(xbgmsharp) #1

Hello,

Which bluetouh module should be include to build the kernel?


Bluetooth on latest image: ubuntu 16.04 V1.2.1 BT and WIFI AP mode are working fine 2017-11-27
(Frank W.) #2
+CONFIG_BT=y
+CONFIG_MTK_COMBO_BT=m
+CONFIG_MTK_COMBO_BT_HCI=m

(xbgmsharp) #3

where in the menuconfig i can enable CONFIG_MTK_COMBO_BT?


(Frank W.) #4

You can search with / in menuconfig

I have added these options to my defconfig in debug-branch…

simply “./build.sh importconfig”

Else the option is in device drivers - misc devices - mediatek periferals


(xbgmsharp) #5

Thanks. I did remove some un-need driver from your config.

It does not compile

/wmt_idc.h is only loaded if CONFIG_MTK_CONN_LTE_IDC_SUPPORT is set…this is a LTE-Driver and can’t be compiled because of missing android-headers

which drivers do you remove? BTIF is needed for BT and Wifi

some other drivers are listed in Kconfig which are not working too…must be reworked,but first i want to get other things working

ok works, first time if initiate the device it hangs. then the firmware load it and it is fine.

(Frank W.) #8

Please try to reproduce the problem (step-by-step) and then try that with kernel 4.4.70, open an issue there…i have only ported it,but did not know much about internals


(xbgmsharp) #9

Thanks, I might give a go with the project_test branch on 4.4.70

i will wait for the dev to be stable prior to i replace my current soekris as a router.

The HW spec looks nice but it is NOT ready for production yet.


(Frank W.) #10

gary (or any other) must be able to reproduce this error, to fix it…


(xbgmsharp) #11

First ensure you have the wifi up and running prior to test bluetooth as the BT adapter is bundled with a Wi-Fi card.

The device is detected and running but no LE support. My goal is to connect a BT speaker. Only hci tools are working, no bluetoothctl bluetoothd for some reasons.

Bring up with:

bluetoothd is afaik part of bluez…have you enabled bluez (maybe separate stack also needed) in kernel too? error-message of bluetoothd?

imho wlan must not be connected but the chip must be started before with wmt-tools (wmt_loader ,stp_uart_lancher)

on which step you hang or is not desired result?


(xbgmsharp) #13

To run bluetoothd you need rfkill in the kernel. I manage to avoid the error, but doesn’t solve the issue.

CONFIG_RFKILL_LEDS=y
CONFIG_RFKILL_INPUT=y
CONFIG_RFKILL_GPIO=y

(Frank W.) #14

added that and some other now in main


(xbgmsharp) #15

Did some more test, same OS but with kernel 4.4. LEscan is working but unable to pair or set a connection between BT devices. Something is missing in 4.14 to allow LE scan to work.

bluetoothd is still not working.

(Frank W.) #16

which OS do you use? which device? pin-protected? BT-version? bluez-utils (which version) installed?

does it work with 4.4+ubuntu?

BT-Speaker may needs some from the audio/multimedia-stack (internal audio-chip maybe), please first try a “simple” BT-device line mouse/keyboard to test if BT itself is working, the complexer devices like audio/multimedia

maybe passkey-problem: https://debianforum.de/forum/viewtopic.php?p=671148#p671148 (compile passkey-agent and use it to set PINcode)


(xbgmsharp) #17

For all my test i use the same system, eg: Debian stech.

There is nothing related to a BT-Speaker yet as it is pure BT scan and connection. It should be able to list all BT devices available.

you can connect your speaker with 4.4.70?

then we must search the localtion of that error…i’m currently not at home so i can’t search the source-tree

error seems to be here: https://github.com/frank-w/BPI-R2-4.14/blob/8c3ec0a9f038d0089a28ee306fea1efdb41ad810/drivers/misc/mediatek/connectivity/common/conn_soc/core/wmt_ctrl.c#L274

obj-$(CONFIG_MTK_COMBO_BT_HCI) += bt/

seems to be missing in drivers/misc/mediatek/connectivity/Makefile

i assume that there are coming compile-errors, i had not ported something in the BT-Driver, merged after wifi was working

mhm…the bt-folder is removed also in 4.4.70…strange…

@garywang have you an idea what is missing?

created branch debug_bt…but currently i’ve found no difference to 4.4

there are WMT_DBG_FUNC, but i don’t know how to show that messages…

@xbgmsharp can you add printk() in that file in that function to see more whats going on?

i assume that the read from BT is failing…function mtk_wcn_stp_receive_data is in file /drivers/misc/mediatek/connectivity/common/conn_soc/include/stp_exp.h and drivers/misc/mediatek/connectivity/common/common_detect/wmt_stp_exp.c


(gary) #20

The reason why I removed BT folder is that I implemented BT support in linux-mt/drivers/misc/mediatek/connectivity/common/conn_soc/linux/pub/stp_chrdev_bt.c.
