For those that have used a FCC/IC stamped and certified WiFi or Bluetooth module for example Laird or Espressif for an IoT product, where the other aspects of the design would typically be low risk or benign from a EMC perspective i.e. opamp type circuits or no or low power switch mode converters < 10W. Did you breeze through EMC testing with a comfortable margin (say 3dB) or did your design need tweaking after prescan?

My experience to date has been good as long as the remainder of the circuit is low power with a decent ground plane, and not quite so good with higher power circuits.

Hmmm, no answers to this so far...

I'm very curious myself - have been developing a BLE product, using an FCC certified module.  But I've never done FCC/CE RED/RCM testing before.  Should be ok, but a little concerned that I'll spend good money on testing (even a prescan will cost), then have to spend time trying to revise the design, then more money and maybe still repeat.  So it would be great to get some sense of how other people have gone.

And as an aside, it seems that EMC testing is hush hush.  Secret engineers' business?  There's always plenty of discussion of component selection, PCB design and assembly, but from forums like this you'd almost think that hardly anyone gets their designs tested!
