Communicating to Bridge Node with SPI

Hi :slight_smile:

I´m trying to comunicate with the Bridge Node using an Arduino. I saw in “Product_and_Design_Documents” -> “DWM1001_System_Overview.pdf” (page 13) that the Bridge Node comunicate with the Linux Host by SPI TLV, but there´s no TLV to get the informations that the bridge sends. How can i comunicate with the Bridge by SPI?

Hi Rarafa,

The interface with the bridge node is currently not documented, so there is no straightforward way to communicate with it.

Thanks
Yves

Hey Yves_Bernard.

I was reading the “Dwm1001 Firmware API Guide” and i found the TLV command “dwm_backhaul_xfer”. What about it? Can i receive the datas from the Bridge node with this?

Hi,

Well the issue is that the data to send with the dwm_backhaul_xfer api is not documented, making it not very useful.
