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?
