QCA6174 bluetooth Validation with i.MX8QM MEK Android Pie Automotive

[redwanmohamed]

Hi NXP Team,

We are trying to validate the QCA6174 PCI module with i.MX8QM MEK platform and we are able to successfully test WiFI. But when we try to validate Bluetooth we are facing below issues. We have even tested with Prebuilt binaries android_p9.0.0_2.1.1-auto but no luck. We also tried to enable basic kernel configurations and verify without any luck

Hi Diego,

we are able to get nearby Bluetooth devices listed with non car build but Connect fails (even though same changes has been done in car build it doesn’t even list the nearby devices) . What we observed is a2dp source is enabled and not the sink - we tried to modify the bt_config but output remains same

we have observed the same behaviour with last week android 10 release from nxp. Please provide some pointers on this

Thanks

AMR

Hello,

Unfortunately, QCA6174 module is no longer supported by us. Furthermore, i.MX8QM is still in pre-production and most of the information could be subject to change. 

Best regards,

Diego.

[redwanmohamed]

Thanks Diego for the update. Could you please let us know which the Bluetooth module is evaluated will go with the same chipset

[diegoadrian]

Hello,

For the moment the supported Bluetooth/WiFi chip is the following one:

LBEH5UL1CX from Murata.

Best regards,

Diego.

[redwanmohamed]

Thanks Diego for the valuable information. Could you please let us know the Android NXP release version which we can refer to validate that

1CX M.2 Module - Embedded Artists  Hope this is the module you are talking about

[diegoadrian]

Hello,

It is the same. However, the connection of that device is thought PCIe. You will need ti implement the driver to make it work with PCIe.

Best regards,

Diego.

[redwanmohamed]

Hi Diego,

Could you pls tell us more about the PCIE driver you are talking about. Hope we have enabled it and not facing that at the moment. Any other pointers would also help us moving forward

[redwanmohamed]

Not sure how to add patch - pasting the changes here

Hi Diego,

We have procured LBEH5UL1CX from Murata per your suggestion. Found evk_8mq have been evaluated with that module and did the required changes to mek_8q board - we are getting below log. Attached the patches we have done for validating bcm4356 chipset

Could you please help us resolve this - we are working on this for the past 1 month with the 2nd module (earlier qca6174 per RN and now bcm4356)
