Has anyone successfully tested a connection to Azure IoT over a Cellular PPP connection?
Using 2.1.0-Preview 3
I can successfully connect over hardwired ethernet. When I switch connection to using Cellular PPP it locks up and crashes with no errors reported. (Debug disconnects) It takes a physical reset to reconnect to the board.
-
The Azure code is the same between the hardwired ethernet and cellular. Including the certificate.
-
when using the cellular connection there is no hardwire ethernet code. The cellular is the only network connection.
-
Before attempting Azure connection using PPP I can successfully set the time using NTP and also download some data from the internet to test the connection.
Any suggestions on how to proceed?
Update: I tried to connect to an HTTPS connection using the TLS example in the Tutorials. It works with hardwire ethernet but not with cellular. Could it be that it can’t negotiate a TLS connection over PPP?
