Hello all,

I would like to close out a theory: figure out that the Jolla C and Aqua Fish has NFC or not. James officially denied it here: however by taking apart my AF I have realized that there is an NFC like PCB antenna in the bottom half and an RF cable is present in the device which is connected to the mainboard through a connector silkscreened NFC:

The references to the NFC chip are in the kernel's DTS sources too which seems to be compiled in too. I have not been able to communicate with the chip yet, so it brings up the question if the manufacturer populated it or not.

To ensure it I would need to take off the metal shielding caps from the main board which is a little bit risky to perform on my primary phone. If someone has a dead unit (washed/sunken/whatever) preferably in Europe please let me know. I need only the mainboard.

Plan B: I used to work in a manufacturing company where we had industrial XRAY machines for soldering inspection . If someone having a JC/AF device could take XRAY images from a phone the presence of the NFC chip could be determined.

I only half qualify to your request here, I have access to industrial X-Ray but only own the Jolla1 phone myself. So if someone would lend me a JC/AF I would be happy to put it in the X-Ray ;)

I would recommend you to share the country/region/city where you are accessible to increase the possibility to find someone nearby.

In the DTS file the Unitronics engineers mentioning NXP547.

You can find a --khmmm -- confidiental datasheet here:

It is in a VFBGA49 package, and I assume it is in the region marked below according to the NFC antenna cable connector location:

Is the datasheet link working correctly?
My "region" is somewhere in Sweden ;)

Ah, datasheetpdf forbids direct linking. Here is the link to the datasheet:
