Dwm_usr_data_write format

Hi,

I´m here with another problem after I solved the other problem I had. We are trying de dwm-range-iot code to send the distance between the tag and the anchor via mqtt. The problem is that we don´t know the data format when we receive the data. We know that is base64 but we don´t know how to send it as ascii or plain text. Is it possible or do we have to decode it?

Thanks!!

Hello,

per chance I just did something similar.
The IoT-data published by the MQTT Server under the topic “dwm/node_addr/data/” should be an ASCII JSON String. In the payload filed the IoT data as far I remember is also ASCII.

Please correct me if I remember incorrectly.

Best regards,
Chris

Hi Chris,

We solved it thanks to javascript. When we receive the data is in base64 so we use atob function in order to decode the data received.
