Sending messages asynchronously to nRF9160

[RJengr]

Hello,

We are currently using the HTTP sample on the nrf9160 and are able to send messages using POST commands to the web server. We were wondering if there is a way for our cloud to send a message to the 9160 asynchronously without a POST request response from the 9160? I see it may be difficult to run an HTTP server on the nRF, however is there a pipeline for sending a message to the nRF cloud and that has a heartbeat link with the device, or some other method?

Thanks,

RJ

Yes, there is. However this requires the device to be connected using MQTT in order to receive the message. HTTP is a poor choice for cloud-to-device communication and should be avoided, because it is a client-server architecture and expects the server to up all the time. In your scenario the nRF9160 would need to act as the HTTP server.
