Hi @alex ,

I have a working setup with the same configuration as you are, Raspberry Pi Zero 2W with Seeed Studio’s Xiao Halow module. I can achieve up-to 10Mbps between 2 RPi.  
I wire my RPi as shown below:

 ![Raspberry_Pi_Zero_2W_with_Xiao_Halow](https://us1.discourse-cdn.com/flex001/uploads/morsemicro/original/1X/2740a3e606905070839bba424a7c6242e1397850.jpeg)

Some difference I have with you setup are:

- The DTS I use is exactly the same as the one in the [AppNote](https://www.morsemicro.com/resources/appnotes/MM_APPNOTE-24_Linux_Porting_Guide.pdf)
- Modify the morse driver with the chip reset changes that’s mentioned [here](https://community.morsemicro.com/t/how-to-use-both-the-mm6108-and-the-built-in-wi-fi-on-the-raspberry-pi-zero-2w/485/4)
- I do not bridge the BUSY and WAKE-UP pin. So the module is ON all the time.
- I load the morse driver with 20MHz SPI Speed

```auto
insmod morse.ko bcf=bcf_fgh100mhaamd.bin spi_clock_speed=20000000 country=US

```

I could never use 50MHz SPI speed using the current wiring, the SPI comm always fail. You can also pass debug\_mask=1 when loading the driver to enable debug messages.
