I'm using a microcontrollerboard FEZ with integrated SPWF04Sc from GHI-Electronics to load sensor data to Azure Table Storage.My test-application ran fine with transmission through SSL sockets for some days with several hundred transmissions until it...

Thanks for your answer,the BaltimoreCyperTrustRoot certificate is loaded by the driver of the FEZ board via the AT+S.TLSCERT command to the SPWF04Sx. This root certificate was not changed in the security chain. To doublecheck I freshly loaded this ce...
