Hi Sheetal

I am using murata (wifi + bt chip)-LBEE5HY1MW with imx6ul.I am using kernel version 5.4 (yocto zeus)

Firmware for bluetooth is already present in /etc/fimware - BCM4345C0.1MW.hcd

Hello:

  it is not enough to judge what happened with only below log:

Failed to connect: org.bluez.Error.Failed
[bluetooth]#

any other logs for the issue , sniffer or other system log ?
