Has anyone got bluetooth on SD8787 working on a recent Android? 4.2 or 4.3?

adamlee — Wed, 13 Nov 2013 08:24:55 GMT

Hello everyone, following the discussion here, I was able to get wifi running.

And I was wondering if anyone has succeeded in getting bluetooth to work in Jellybean.

I will begin working on this tomorrow, and I will post all my findings here. Hope you can do the same.

Thank you!

I also create a discussion about sd8787 bluetooth on MX6Q. Because android 4.2 use bluedroid as BT stack,we must write vendor library for bluedroid stack.

Marvell released a character device based bluetooth driver named mbtc and based on it Marvell provide a Bluedroid glue library (attched file).

Unfortunately, BT is so unstable on my board. You can try it based on what I provide.

This is my thread iMX6 kernel crash with Marvell Bluetooth module enabled

Thanks Raymond. I am building an image with the vendor library. I am pretty sure I have some kernel configs not right, but we will see.

By the way, where did you find this? I couldn't find it in Marvell's website.

[update] My build fails with this. I am missing libMarvellWireless library in my source. Not sure where to get this from.

I get the vendor library from Marvell distributor. The whole android source code tree based on Marvell PXA986/988/1088 and a sample works both for wlan and bt.

I think you should check your Android.mk for libMarvellWireless and MarvellWirelessDaemon.

The relationship among them:

Android WiFi->hardware/libhardware_legacy/wifi.c->libMarvellWireless->MarvellWirelessDaemon<---libMarvellWireless<-libbt-vendor.so<--bluetooth.default.so(bluedroid).

| | |

wpa_supplicant+Marvell 802.11 private library | |

| | |

linux ioctl | character device HCI interface

| | |

Marvell Wlan driver (wireless interface)<-------Insert/remove driver module --------------------- -->mbtc driver

If something wrong ,you can point out.

Thanks Raymond. I've contacted Marvell also. It's been a couple days.

I will promptly let you know if I have new development!

Do you have a github I can look at for your device trees? The new Galaxy Tab 3 7in SMT-21XX variants have the marvell pxa988 and we are trying to port cyanogenmod to this device. We are located over at XDA-Developers and it appears you guys pretty much have knowledge on Marvell. We too use the same BT and Wifi driver.

Hi Carl, my BSP can be found here. However, you won't find the wifi/bt related binaries here, because I haven't pushed them yet. I need to get clearance first. Check back soon!

So far I am stuck at here:

Bluetooth on Pepper · Issue #5 · gumdroid/manifest · GitHub

E/bt_hw ( 713): !!! Failed to load libbt-vendor.so !!!

All my .ko are building fine.

adamlee — Tue, 31 Dec 2013 19:00:31 GMT

Raymond, can you share the source for MarvellWirelessDaemon and libMarvellWireless? My source does not generate these two objects.

Also, are you using /etc/bluetooth/bt_vendor.conf file at all to specify the location of the firmware and the device node (/dev/mbtchar0)?

Thanks :smileyhappy:

Update Marvell driver to LINUX2635-14 66 9 p75-M2614301 can fix bluetooth crash issue.

Hi Raymond, I am also trying to enable bt on sd8787 after integrating the driver. i am getting below error

E/bt-btif ( 45): ...preload_wait_timeout (retried:0/max-retry:0)

I am still using default athros lib-vendor library, Can your please share your vendor implement for bluedroid stack?

It will be really helpful for me.

Hi Raymond, we are using the same module for our customized imx6 board, we didn't use Marvell's libbt-vendor.so for the bt module, instead we ported 'Bluez+bt8xxx.c' to replace the original 'Bluedroid+char device' for Android 4.2.2. We almost get there, but we always encounter a timeout issue while bring up the BT module. The error message list as belows: BT: module_cfg_cmd (0xf1): timeout sendcmdflag=1, and then the BT won't bring up. It must happen after several times of BT off-on status reversed. Once it happened, nothing but reboot can bring up the BT module again. So, have you ever encountered such timeout issue? What about the current status of your stacks porting? My mail address is 'xj.gan@vantrontech.com', I am expecting a further discuss with you about the Marvell BT issue, thanks!

Thanks very much, your help is invaluable !

I would like to point out, that MarvellWirelessDaemon / libMarvellWireless are actually optional (having role much resembling that of wifi.c), and can quite safely be left out.
