MSP432E401Y: MQTT DATA RATE : I am not able to send more than 980 bytes of payload of data to the mosquitto broker. WHAT IS THE MAX PAYLOAD LIMIT WITHOUT LOSS FOR THIS HARDWARE??

Part Number: MSP432E401Y

Tool/software:

I tried to send a payload of more than 980 bytes of data through a the dev board . I connected it to a CE510 PHAROS Router and have a laptop running a mosquitto broker connected to one more CE router. But the data gets lost if the payload is more than 980 bytes. Is there a way to increase the the payload size without data loss . What is the issue?? I AM USING TI RTOS CODE FOR THIS ..

Is this your own custom code or you were running some stock example? If you were running an example, which example was it?

I'm not familiar with a CE router vs a regular router. Have you tried the same code on a regular router? Do you see the same problem?

Can you use Wireshark to diagnose the problem?
