NRF52832 antena set-up

[Joseph]

Hello,

I'm currently creating my own custom board for NRF 52832.

I put everything together, but I can't detect my custom board through Bluetooth using the NRF connect app. 

I'm using QFAA and QFAB QFN48 with DC/DC regulator setup.

Here I've attached the schematic of my custom board and all the components.

I'm new to designing an antenna for BLE. I believe there's something wrong with the antenna design. 

Please let me know if there's anything wrong with this design. 

Thank you!

Thanks for the detailed posts, these were very helpful. We're going to look into a few of the things that you mentioned and get some more information. If things still aren't working after we try some other stuff, do you think there's any possibility we could quickly meet over zoom to discuss this? I'm not sure if that's something that is ever done for devzone posts, so if not no worries. Either way, we'll give what you mentioned a try and reach out once we've done so.

Regards,

Connor

We dont do this. Only way to get this is through our sales department but that is not something that happens often.

But I will happily answer any questions here and to my best to help you reach your goal here. 

So feel free to keep asking here and I will do my best to help out. 


I went digging though some of the other tickets here related and found an image in another ticket, looks like you are manufacturing your own pcb's here. Either machined out or with etching, this does work well and is relatively fast but can be difficult for more complex designes that involve radios. 

I also did this some time ago and even with a design that was close to the reference design it did not yield great results as many of the PCB's did not preform well. I also hade to hand stich the top and bottom layer together with thin wire or lots of solder to make sure there was a consistent grund plane here, process is a lot more involved and there was room for more human error in my experience.
