Hello David,
I'm working on a project that connect to AWS IoT service over GSM/GPRS modem. I want to port wolfMqtt Client on freescale Kinetic 20 Series microcontroller. k20 series controller doesn't support RTOS. In cuurent scenario, I am using GSM/GPRS modem (SIM 868) to send data over TCP which is working fine.

As we are using k20 microcontroller which doesn't have TCP stack on it, So can we use wolfssl & wolfmqtt to send the data over k20 controller's UART to the SIM868(GSM/GPRS Modem) which is having TCP stack?

Thanks in advance!
