We found the strength of BT signal to be too low
As suggested by FAE, want to load path to fix this problem
But after setting the patch, it is found that the patch should still not be loaded successfully
Is it correct to put .hcd in /etc/firmware path?
If patch not found is displayed, what is the possible reason?
Solved! Go to Solution.

Hi,
Have you build the Yocto image and rootfs populated in your machine? The readme says that during hciattach bluez queries for the chip ID which will be used for later while flashing the patch. In your case after hciattach I see an error which says "Patch not found".

I request you to check in the murata community regarding the process of applying the patch to the modules.
Thanks,
