I am using the NXP evaluation board IMX 8MPLUS with combined wifi and bluetooth Azureware chip (AW-CM276MA PUR) . I am having trouble enabling the Bluetooth module.
I followed the instruction from the document: “UM11483 Getting Started with NXP Wireless Modules for i.MX 8M-Quad Platforms”.
I could successfully enable the wireless module. But for the Bluetooth, first I execute a command “hciattach /dev/ttymxc2 any 115200 flow” as suggested in the document and the result is as expected:
Setting TTY to N_HCI line discipline
Device setup complete
After that I run the command “hciconfig hci0 up” but with timeout errors:
[ 132.478107] Bluetooth: hci0: command 0x1003 tx timeout
[ 134.494103] Bluetooth: hci0: command 0x1001 tx timeout
[ 136.510105] Bluetooth: hci0: command 0x1009 tx timeout
Can't init device hci0: Connection timed out (110)
I read manuals very carefully, searched the nxp community and did whatever I could think of without success. Could you please help me solve this problem?
Thank you in advance
