MQTT implementation on top of OpenThread stack

[Shahabuddin Mohammed]

Hi,

I need some advice on implementation of MQTT on Thread devices.
I am planning to use MQTT on top of LWIP TCP stack over OT stack.

Question: How to pass TCP packets to OT? Should I bypass the UDP path by accessing Ip6 send/receive:

Ip6::SendDatagram
Ip6::HandleDatagram

Thanks,
Shahab

Hi Shahab,

OpenThread does not currently provide a TCP API.  If you have your own TCP implementation, you could try using the following IPv6 APIs to send/receive raw IPv6 datagrams:

ThreadError otSendIp6Datagram(otInstance *aInstance, otMessage aMessage);

void otSetReceiveIp6DatagramCallback(otInstance *aInstance, otReceiveIp6DatagramCallback aCallback,
                                     void *aCallbackContext);
