DWM-1001-Dev send custom messages

Hi I wanted to ask if it is possible to send custom messages between anchor and tag. I think it is advertised for the module, but I cannot find a call for that in the API.

Hi Christophe,
This has been asked a few times, please use the search option and look for it (eg before asking)
for example: How to send custom message over UWB? DW1001
