Lucid Air's Number One Software Issue?

[mikecronis]

"Fla-Key FOB". Honestly, I think it might be the freq. interference and battery drain.
Normally it's 315 MHz for most cars. Tesla is 6 GHz, just outside of the current 5 GHz freq. making interference less of an issue (for now) except some areas are experimenting with 6 GHz like in subway systems. Some decent phones are able to hop over.
Lucid is using 2.5 GHz which is close to WIFI signals as a BT signal.

I have heard that the AIR uses BLE. - see frquencies below. It is unfortunate that we have so little (none) official info from Lucid.

Someone with a Spectrmu Analyzer should check this.

Bluetooth Low Energy (BLE) utilizes 40 channels within the 2.4 GHz band, each spaced 2 MHz apart. These channels are numbered 0 to 39, with 37 dedicated to data transmission and 3 used for advertising. The advertisement channels are 2402 MHz, 2426 MHz, and 2480 MHz.

It does use BLE for the fob/phone

Gravity uses UWB

It is true that the reliability of Lucid's unlocking system is inversely proportional to the number of people watching.

It's a more complex formula than just that. It definitely takes into consideration the weather and the number of things in your hands.

No need to break out the spectrum analyzer, install nRF Connect (a great BLE dev/debugging tool from NordicRF) on your phone and you can browse BLE devices. The Air shows up, as do all four corners of my neighbor's Rivian every time he drives by.

Thanks for the more accurate equation and the nRF info. I think Nordic is one of their chip vendors. In a post a few months ago I think I found the Fob maker.

Is the card NFC? Does the FOB also use NFC for those who say you can rub it on the B pillar? Thanks

Yes and yes. Standard issue NFC card and separate NFC chip in the fob. I've read it with a random NFC reader, though it has proper auth/encryption so not much to do with that. At least if you have an iPhone you'll also notice holding your phone up to the B pillar camera will pop open Apple Wallet, because the phone detects it as an NFC reader and wants to treat it like a payment terminal or transit scanner.

If you value security (some do) I'd be cautious with what CarLinkIt installs on your Android device. I've held-off and just use BT audio for Waze+Music for now... Just a heads-up.

Can you expand on what CarLinkit installs on your Android phone.

 

[segbrk]

Can you expand on what CarLinkit installs on your Android phone.

It doesn't. Your Android phone treats it just like a head unit that supports AA. That said, it is a full computer with an internet connection from a Chinese brand nobody has ever heard of that you're sharing your contacts, location, navigation destinations, calendar events, etc. with.

Yes I didn't think it installed anything on the phone.

I thought Carlinkit worked with Android Auto or Carplay without any additional SW? Is that not true?
Please ignore.. perils of reading from the top!

The phone and the fob are equally reliable for all of our vehicles. walk into the garage and they all open pretty simultaneously. I’m not sure if this is a glitch, but seems to work 98.8% of the times.

Except when I have guests over, lol. Then 70/30.

For me, it is 100% reliable only when I am getting to the garage to pick up something from the shelf, or passing through to my yard. If I get out to the garage with the intention to get in the car, it opens like half the time.. I think it has an undocumented mind reading feature

Thanks much!! Does nRF permit you to see the bit sequence sent for open/close and trunk?

No, no way to peer into that data without lifting the (crypto) keys from either end, BLE traffic is also encrypted.

 

[Steve181]

Thanks - not surprised. I wonder if enough of us communicated with the key fob vendor that they might have a plan for a new product or retrofit that would help us. I wrote to them once, but never got an answer.
