I ported our application to the new SDK and my experiments with one faulty bcm20737S showed that the new SDK resolves the issue. This is great news! Thanks a lot.
This is great news. Thanks for updating the discussion.
SDK 2.2.3 on Windows caused very strange errors to occur. LEDs blinking erratically, resets, etc. We think there~s something wrong with the fine timer in this SDK version for Windows.
We finally went back to SDK 2.2.2 on Mac. Now the downloaded code works fine, but the initial problem of about 10% of the boards STOPPING ADVERTISEMENT is back.
How can we solve this problem? It's always the same boards that fail; it's not random. For example, if you have 70 boards and about 7 fail, then if you reset/restart all 70, the same 7 will fail again.
This is not a manufacturing issue, because we have used 4 different manufacturers, and different versions of the PCB layout (which follows your guidelines) and always get the same identical problem.
We need to solve this problem badly!!!!
