Advertising issue with nRF52832 custom board

[Tai]

Hello everyone,

I have been using nRF52832 module from Raytac (link) for my circuit and I got a trouble with sending advertising packages to other master devices. I installed a LED which is similar to setup in nRF52832 PCA10040 KIT for indicating whenever it is sending advertising packages or not. The result is that it sometimes did advertise, and after that it didn't advertise anymore.

Since this module integrated a crystal 32 Mhz inside, I don't think the issue from crystal. I have been searching this error and followed some of previous posts (this) to configure clock source and RAM setting; however, it didn't work.

Below is my clock setting and RAM setting:

Could you please give me any suggestion regarding to configure RAM and CLOCK? Btw, I am using SDK 13 and Sofdevice 132 v4.0.2.

Thanks!

Since I used reflow oven to solder the circuit and BLE module, temperature exceeded the range of nRF52 chip inside module, causing the issue. I replaced a new one and it worked!.
