UWB data transmission between two DWM1001s
#11
Hi Kwileu,

The earlier answer from Zoran stated that it is impossible to send data other than location over UWB with DWM1001 firmware release 1. This is a correct statement.

The release 2 that is currently developed will introduce a new feature allowing to transfer data other than location over UWB. This data transmission will follow a very well defined protocol : the data will go from a DWM1001 to a Bridge node over UWB. The bridge node will transfer the data to a MQTT broker and the user can access it there. 

The last few message were all related to the release 2.

Hope it's clear now.

Thank you,
Yves

Similarly, the kernel is timing critical and should have the priority against other real time applications. Regarding the wifi/ethernet solution, it is used to allow the user to interact with the bridge node and connect to the MQTT broker (hosted on the raspberry pi).

Hello again Yves,

Sorry if i am annoying/boring...

My question concerning running a user appilcation in the same Rasp was related to how to communicate directly to the MQTT broker from this user appliaction. See the attached diagram. I woudn't like to use another controller to host our application, and connect it to the Raspberry either by wifi or ethernet cable. I would like to use the same Raspberry as a single controller to do the whole tasks. Is there a way to communicate with the MQTT broker from this local user application?

Thank you again

Hi Espenciso,

I'm not 100% sure i'll have to double check. I'd say it is ok as the broker can be hosted locally on the rbp3b but don't take it for granted as I am not completely sure.

I'll update the thread once I have a chance to look at it into more details.

Thanks
Regards

Hello Yves,

Any update on this?
Should we consider that it will not be possible to communicate with the MQTT broker from a local user application running in the same Raspberry?

Thank you

Hi Epenciso,

I got a chance to try it today and it is possible to connect to the mqtt broker from the raspberry pi itself as a localhost. 

Thank you,
