IW612/IW611 MAYA-W2 Module Bluetooth bring up

nifroidl — Tue, 13 Aug 2024 16:35:48 GMT

I am using the MAYA-W2 module from u-blox for a WiFi Bluetooth Adapter. Since there is the IW611/IW612 populated, maybe some of you can help me. I can easily bring up WiFi using the mwifiex driver and imx-firmware for IW612 but I am not able to bring up Bluetooth:

root@phyboard-pollux-imx8mp-3:~# hciattach /dev/ttymxc2 any 115200 flow

@pratham_malaviya Yes. In my case it was an HW issue. I had to switch RTS and CTS signal for UART. After that I was able to get the BT interface running

@nifroidl In my case when i don't use flow control (RTS unconnected / Module CTS grounded) the interface work. Which hardware connection did you used to make it work?

@pratham_malaviya Maybe this is your issue. Do you have teh Flow Control Pins available? I think I tried to use the chip without Flow Control and it didn't work.
