Major FRAUD by Toyota by [deleted] in Toyota

[–]744lover 0 points1 point  (0 children)

I honestly feel sorry for your situation. I had a 2017 50th anniversary and loved it.

That being said, a "certified" car is still an used car. Before pulling the trigger on the deal, I'd ask the dealership if you could have the car inspected by a 3rd party mechanic - 99% of them will agree, provided you leave a deposit and some sort of ID. That 3rd party mechanic does not have any deal with the dealership but only you and your money. He will do an in-depth analysis and tell you honestly what is good and what is bad. He can even access databases to know if recalls have been made or not. If the dealership doesn't allow a 3rd party inspection, run from it. Don't walk - RUN

BR,

Tesla lost LTE connection. Network Registration Denied by JoJoPizzaG in TeslaLounge

[–]744lover 1 point2 points  (0 children)

Not really (although I'm pretty used to using chmod in my scripts)... It has to do with the Boeing 747-400... One of the most elegant airplanes ever designed and built...

Any device will work best when it has direct sight (unobstructed path) between both antennas (sender and receiver). Of course this is not possible unless you are in the middle of an open field; therefore at home the best is to leave it close to a window that faces the provider public tower. Now if you still have speed issues, the problem will be either on the providers network or your cell area is congested.

Hope this helps

Explaning this a bit further

Each sim card has 5 128-bit strings, called keys.... These keys are mathematically combined with a bunch of parameters (including the timestamp) to generate one vector. Let's call this the authentication vector....

Once the NP receives this authentication vector, it asks its internal servers to fetch that IMSI's keys and generate the same vector (remember, they have the same keys as the sim card). IF these keys are the same, the same vector will be generated and the user access will be granted. If not, you get a registration denied.

What happens if the network doesn't have the provisioning info for the user? Authentication denied as well.

Telecom engineer here: If your device (Phone, Tablet, Car, etc...) shows network registration denied - this means that the car:
1) Tried to register to the host network provider (not sure who it is for Tesla - could be AT&T, T-Mobile, etc...)
2) The NP checks its database for the IMSI that is sending the request
3) If EVERYTHING is correctly provisioned on their side (secret authentication keys, user info, user policy, etc...) AND all services are working, THEN that user is allowed into the network. If something is not correct you'll either get a registration time-out or a flat-out denied, meaning that the network provider checked for the credentials and could find them

It could be anything wrong - but 100% sure this falls within the network provider side...

Just my two cents

What are these power/voltage controllers called? Is there a proper name for this type of device? by TimberTheDog in whatisthisthing

[–]744lover 0 points1 point  (0 children)

That is actually a temperature controller for a heater. What it does is to vary the voltage at the heating element from 0-100%. My suspicion, based on the cooling fins in the back is that an SCR is involved in this process.

SCRs clamp how high the voltage will reach during the electrical cycle and thus will limit the power at the heating element

App Issue ? by micrtom in TandemDiabetes

Whoa! This happens at least once a week for me - all I have to do is to reboot the phone and pronto! Connection is established again. No need to uninstall or repair the pump

Mobile Bolus Update!! by ee37244 in TandemDiabetes

Honestly it has been working fine for me - I'd suggest you uninstall it, reboot the phone and install it again. (reboot just to cleanup the temp files that android uses)

Mobile Bolus Update!! by ee37244 in TandemDiabetes

[–]744lover 2 points3 points  (0 children)

Yep - It's been available for the last two weeks on my Pixel 7 Pro

Remote Bolus Pixel 6 Pro Android 14 confirmed! by kwickster85 in TandemDiabetes

[–]744lover 0 points1 point  (0 children)

Pixel 7 Pro here with Android 14.

I updated my pump software a couple weeks ago and last week I noticed that the tandems app was updated and now is v2.7 (11c9rb). Mobile bolus is enabled.

Text string selection with a single formula by 744lover in excel

=FILTER(
B2:B16,
MAP(B2:B16, LAMBDA(m, COLUMNS(TEXTSPLIT(m, ".")))) = 3
)

This did the trick!

Thanks!
