This project provides a Zephyr based CoAP peer example for the EdgeX device-coap-c project.
This example will make POST requests to device-coap-c's resource for asynchronously generated data. The example includes sample Kconfig files for both DTLS PSK and nosec security.
The example sends a POST to:
coap(s)://192.0.2.2/a1r/d1/intIn other words the protocol portion either is coaps for DTLS or coap for nosec. The example assumes the device is named d1 in EdgeX.
This example includes a prj.conf to initialize the build. The example also includes two complete Kconfig setups dtls.config and nosec.config which can be copied to ./build/zephyr/.config for a native_posix build.
For a DTLS PSK build, the client identity and key are defined in src/dummy_psk.h. The key must match the key used in the device-coap-c service.
A run of the app sends three POST requests, separated by three seconds. The output should look like:
UART_0 connected to pseudotty: /dev/pts/9
