I am using mqtt library from sodaq (mqtt over tcp sockets).
I am able to publish a message to a topic with it. Integrated my subscription code as well for a topic. But after sometime i am unable to get subscribed messages, publishing works fine every time.
From reference to older thread [“TCP socket fails to read after a short while”] i have tried AT+UPSV?, it gives +UPSV:0 as well.
Kindly provide help asap. I faced this issue at my final stages in delivering of my product.
Thanks in advance
