You could add a backup battery and connect it to the VBAT for RTC backup. then, use the NTP example to poll the time off an internet time server.
Can you send me the the NTP example code?
I'm not sure that I'm allowed to send you the actual code.. but I'm quite sure that specifying the path to the code would be fine:
just call sntp_start_auto_time_sync(..) and you're set ;-).
Please send me the NTP example code as before ASAP. I always get the example codes from you like tftp that doesn't com with SDK 3.1.2.
Thanks in advance
I'll wait for one of the guys from Broadcom to help you with that
