Hi @MJD!
Thank you for contacting NXP Support!

The command that you are using is incorrect, you wrote "modprobe moal mod_par=nxp/wifi_mod_para.conf" and the command is "modprobe moal mod_para=nxp/wifi_mod_para.conf"

Best Regards!
Chavira

Hi @NealZhang

Regarding BT it was TX RX connection issue, check the connections.
