Jolla C might have NFC capabilities
1 Attachment(s)
So, after tearing apart the Jolla C to repair the headphone jack once more.... I saw something that I didn't see before.
There are 3 soldering points with the tag NFC on it... Interesting... |
Re: Jolla C might have NFC capabilities
Might be worth tearing open a Jolla 1 for comparison shots?

Re: Jolla C might have NFC capabilities
There's a thread with a teardown by der_pepe (edit: of the original Jolla) here [1]
He posted some pics of the interior here [2]. And here's the bit about NFC from the first post: Quote:
Edit: there's a few related threads TJC (regarding JollaC and NFC), the last of which from last month [4][5][6].

Re: Jolla C might have NFC capabilities
I'm an electronics noob ...
So, if there's a chip already there, NFC capability might be added by simply soldering an antenna to the contacts? |
Re: Jolla C might have NFC capabilities
Great finding! I looked a bit into the software side of things. First off: There's a driver needed: https://github.com/torvalds/linux/bl.../nfc-pn544.txt
Now to the weird thing: The sysfs entry itself is a hint that there's a driver attached. Also there's /dev/pn544 which indicates that the driver is up&running but modinfo tells there's no driver and there's also no /sys/module/pn544. Lastly: gunzip -c /proc/config.gz | grep NFC # CONFIG_NFC is not set CONFIG_NFC_PN547=y So I really don't know if there's a driver. Now I would love to install some userspace tool to test but which one does support that chip? nfc-tools don't: https://github.com/nfc-tools/libnfc/issues/374 |
Re: Jolla C might have NFC capabilities
Well, CONFIG_NFC_PN547 is a tristate so you could just try compiling it and see what it writes to dmesg on insertion.
I admit it is odd that nfc is set off but the driver is included. No idea which one gets preceedence... |
Re: Jolla C might have NFC capabilities
But we need CONFIG_NFC_PN544_I2C (which is hidden behind CONFIG_NFC), not CONFIG_NFC_PN547. I don't even know what CONFIG_NFC_PN547 is for (linux kernel driver database doesn't know that, too).
Did I say this is weird? ^^ //EDIT: While CONFIG_NFC_PN544_I2C is a tristate, too, http://releases.sailfishos.org/sources/ lags behind for months so no way to compile anything. :( |

I don't know what you have on Jolla-C but this is valid & up-to-date with Jolla sbj1 kernel; https://github.com/KonstaT/sailfisho..._jolla_msm8930 I have used that repository for successiful builds on my device. |
