zpm1066 Do you have a time line as to when your CoAP/DTLS 1.2 CID client with NCS 2.9.1 will be ready?
It’s “ready” for testing ;-).
zephyr-coaps-client - branch ncs_2_9_x
I’m cleaning up the nRF9151 feather work from yesterday, should be finished end of today.
Currently the main missing function is FOTA for the modem firmware.
FOTA for the app works via cellular (CoAP blockwise) and UART/USB/Bluetooth LE via XMODEM.
zpm1066 I plan to setup an Eclipse Californium server on a Raspberry Pi 5 some time next month
I didn’t use a raspi for longer. To connect a cellular device you will need to setup your network to be able to receive UDP from “external” (public internet). If your MVNO provides a VPN, then it may get easier.
I developed a demo server for usage in the cloud, which keeps the data in S3 and comes with a simple javascript web-client. But it requires to run in the cloud and therefore you need to be common with administrating a headless VM.
Californium (Cf) - Cloud CoAP-S3-Proxy Server
A more basic demo would be the
Californium (Cf) - Cloud Demo Server
What makes most sense depends more on your intentions.
