yes,the MQTT protecol is used to build the link with both machines or in IoT development.i want to get the IQ sample for real time.i see it in silab company.because when you want to get the next angle, you should update the IQ samples.so i say that my MQTT is used in IoT decelopment.

i want to get IQ sample from my board of Tx，them i send the IQ sample to my caculation  procedure to get the angle.

Hi,

For getting IQ samples, you must use one of the SoCs as listed on our Bluetooth Direction Finding page.

We have four direction finding examples in the nRF Connect SDK:

• Direction finding central
• Direction finding connectionless locator
• Direction finding connectionless beacon
• Direction finding peripheral

These examples use IQ samples.
