Hi,

Seems that for POS terminals certification BLE4.1 is not allowed.  Is it possible to disble the BLE part in the module using a software patch in the bin file while loading the driver ?  Is suppose it's not possible due to hardware to update the software to BLE4.2.

Thanks

I spoke with the developers and by default the BT ROM in the chip does contain the classic+BLE controller firmware.

However, the software running on the MCU explicitly powers on the BT portion and configures the chip.

If the BT init API is not invoked, then the BT chip shall not be running.

Hi, thanks for your feedback.  Could you please ask if its possible to get a patch to disable the BLE part of the software and just allowing classic BT when the processor loads the driver.  Or is the only option to not use the BT parts at all ?

Can you explain what you mean by enable BT classic and disable BLE? Currently, after enabling the BT chip you may choose not to advertise BLE/scan for BLE; and this would be the equivalent of ‘enabling only BT classic’.

I wanted to check if it was possible to get a rom with only Wifi + BT without the BLE part.  So your suggestion is to do this on linux drivers level ?

You cannot remove BLE from ROM.
