CSR8510 A10 BLE dongle driver for A20 humming board

[Nithin Chakravarthy]

Hi,

I am using  sunxi 3.4.61+ kernel. I have cr8510 ble dongle. 

I have installed Bluez nad necessary packages. 

After connecting the device, I am not able to get hci devices.

Where in my x86 PC i am able detect device. here kernel is 3.19

So any driver is required? 

or

Is there any way to configure BLE device.

Hi,

Hi,

 

Is there any way to configure BLE device.

BLE works okay only with modern kernels (3.18+). Before that it had many problems starting from missing/wrongly implemented features ending with soft lockups.

Hi,

But device is not at all detecting as usb device.

here kernel log

<6>usb 5-1: new full-speed USB device number 2 using sw-ohci

<3>bluetooth: exports duplicate symbol baswap (owned by kernel)

[   94.643972] bluetooth: exports duplicate symbol baswap (owned by kernel)

<3>bluetooth: exports duplicate symbol baswap (owned by kernel)

[   94.661251] bluetooth: exports duplicate symbol baswap (owned by kernel)

whats is meant by "exports duplicate symbol baswap (owned by kernel)"?

how can i solve this

When I tried to insert bfusb.ko module. I got some error

[  273.895355] bluetooth: exports duplicate symbol baswap (owned by kernel)

FATAL: Error inserting btusb (/lib/modules/3.4.61+/kernel/drivers/bluetooth/btusb.ko): Invalid module format

Means exactly what is said - some module tries to export symbol that was already exported.

 

how can i solve this

Use kernel and modules that do not clash with each other. Compile and use https://github.com/linux-sunxi/linux-sunxi/tree/stage/sunxi-3.4 (read wiki http://linux-sunxi.org/Linux_Kernel)

You are trying to insert module that was not meant to be used with your "3.4.61+". You should never try to insert modules from different kernel versions unless you really know what you are doing.
