nRF52832 BT832XE randomly disconnects

[mbates14]

So, after using my Devkit and everything working OK as far as I can tell, I decided to order up a bare BT832XE module and place it on my PCB. 

Flashed it with the same firmware inside SEGGER using the Nordic PCA10040 devkit. 

Seems to connect, everything works fine. for a little bit. Then I will get a random disconnect. It does not show up at all in the debug terminal. as far as it knows, it still thinks its connected. 

When I hit pause, it stops at DEADBEEF. With no rhyme or reason as to why. 

I tried recompiling as debug, and then tried again. Same thing. the disconnects are random. it can happen 30 seconds in, and it can happen as late as 4 to 8 minutes. But it ALWAYS happens. 

I tried adjusting the Clock to 500 with its internal oscillator (not using a crystal externally). No difference. I even tried adding extra bypass capacitance near the module on my PCB, the voltage going in appears to be stable so thats not it. 

Any thoughts?

Nope, nevermind. Yet another fallacy. I cant track down the problem at all. Its totally random, I disabled the communication error traps, and that fixed my crashing when grounding the RX pin, but it still did NOT fix my problem. I can simply just pickup the PCB and wave it around, and itll disconnect. But I can twist on the board, and it doesnt. I really dont get it.

May I suggest to try a different module.  Like this one https://www.crowdsupply.com/i-syst/blyst-nano

Wont work. Not enough output power. the +19 to +20dbm that the BT832XE produces is crucial.
