Hi all
I have a cobra running SDK 4.3.6 and tried the latest PPP code from cellular radio to connect to a webpage and send some variables. The code is working ok.
I’m using the same cobra board to test RTC, everything works ok, my board goes to deepsleep and wakes up after 2 minutes.
When i joined the two pieces of code, the RTC doesn’t work anymore, it always wake up after 1 minute. I’m using the board without VS.
If i comment the part where i power on CR, RTC works ok, so it seems that CR conflicts with RTC…
Here is my code, i had some comments on it :
