We are trying to interface the external peripherals to the SC20 Smart EVB kit with Android Version 7.1.2 SDK. We are facing problem when we are trying to test GPIO, UART with demo app. We are getting a error stating “/dev/ttyHSL0 Open Failure!” for UART and “Error: Value read numerical failure” for GPIO. We also need the demo apk to test I2C. Please do revert back with the solution and provide a link to the demo apk to test the I2C at the earliest.
Thanks in Advance,
