Hi
I have a problem in our modules. some of them will reset when advertising.
There is a LED can indicate this problem.
In normal state, the LED will turn on when the module start advertise,and the LED will turn off after 1 sencond.
In problem modules, the module will reset when advertising .The reset occurs after the LED is turned off for a few seconds, and the module will restart.So you can see the led is flashing constantly.
我有使监管机构,使用延长睡眠. But most of modules work well.Only a few modules have this problem.What's the cause of this problem? Is there a solution?
Thanks!

Hi xavier1989,
I am not able to determine the reason for some modules reseting when advertising, you will have to provide some more information, than simply mention that some of them reset while advertising, you will have to check what leads to this kind of behaviour via debugging and check what causes that, is it the watchdog, or Hardfault exception ? Since you have modules that operate and other that they dont (i suppose that all of the modules are using the same fw) i would assume that this indicates that your problem is on the module's hardware and not on software side. Perhaps this has to do with the module's assembly or bad solders etc.

Hi MT,
Thanks for you reply!
All of the modules are using the same fw.
You say maybe the hardware cause this problem,I think so.
When i remove the DA14580 chip and re-solder it, the module has same problem.
But when i use a new DA14580 chip to instead of the problem module's chip, it works well.
So i think 580 cause this problem on hardware side. Because i use a new chip instead of the older,and the fw are same.
There is an important thing.The module is reseting after the chip sleep.
I will try to debug and check what causes this.
Thanks!
Hi xavier1989,
To have numerous of defect 580's sounds quite impossible, so perhaps something in the manufacturing procedure causes damage on the 580's that you are using.
