Returning OK from endpoint



  • We have a server that we send our data to. Is it possible to have it send a simple OK message back to our device, so it knows to resend if it doesn’t get a response?



  • @sopwafel You could, but be aware of using PSM and expected latency. Your device might be sleeping again before it had the chance to receive a downlink message. I don’t know if it’s possible to use in combination with the T-Mobile CDP but you might want to take a look at LWM2M and CoAP. These protocols have acknowledgements build in.
