      Per this discussion here: Prototype boards are failing with issue similar to one previously reported

       

      I'm having a very similar problem and it looks like the previous user never found a solution.

       

      I have some 20737S modules (4 out of 150), that stop advertising after 10-60 seconds. Even using the example code "hello_sensor" in the SDK, it makes no difference. I have changed the crystal warm up time to 5000ms and it hasn't helped the problem. The problem is definitely related to specific modules. I've also been unable to make a reliable test for this in production, as it seems that when a board is first powered up the advertisements might last several minutes, but then thereafter it lasts 10-60 seconds.
