Re: OTA2 fix list

[ Edited ]

No, OTA2 didn't fix the GPS problem. OTA2 did change the gps.conf (or gps.config) script, I believe. But the problem is deeper than that. Adding a WWAN card and a SIM will instantly make your GPS function perfectly, so it is not a hardware issue. It is entirely software and Lenovo not setting it up right.

 

Several people have tried diagnosing the GPS problem, and their work looks good. Lenovo has not officially admitted to what the problem is, though. In fact, up until a month or so ago, Lenovo was clueless as to what was happening at the same time users were drilling down and finding the source of the problem.

 

Check the first page of this thread for an ALMOST up to date list of what OTA2 has changed (February 2 was the last update there, and several things have happened since then...)

Re: OTA2 fix list

WWAN card is for adding 3G right and the SIM card activates it right? Sorry not too tech-savvy . But I would have to buy the card open the tablet, voiding the warranty to get the WWAN card in? Whew maybe I can live without it?

Re: OTA2 fix list

Yeah, the WWAN card and SIM just give you cell/3G/4G internet access. There are other threads here on how to do this, but you would have to spend $100 bucks and open your TPT to add the WWAN card and also get an account with T-Mobile, verizon, or whoever . . .  That it also fixes the GPS just means Lenovo's design was buggy -- like they only tested with WWAN units and never even tried using a WiFi-only model.

 

OTA2.5 has been announced as coming soon, but I have not seen a list of what it fixes. This GPS problem appears to be easy to fix if Lenovo would just try, so hopefully this month or next everyone's GPS will finally work normally.

 

Regarding WWAN, I think having a cell phone that you can WiFi tether to is the best way to have an always-on connection for your TPT -- and the 7-inch tablets that are coming down in price and are more useful on the train, while out and about, or even while lying in bed. The cell phone carriers would love for us to get a new SIM and a new account for every device we have, but it would be ridiculously expensive. Until they change course and let us use multiple SIMs on one account, WiFi tethering is going to be the way to go.

I am not sure there is either a hardware or software problem with the GPS unit on the ThinkPad tablet. Some time ago I read this tablet has an assisted GPS inside; can someone confirm that A-GPS should work as an standalone system when no WWAN connection to an A-GPS server is possible?

Re: OTA2 fix list

I have a 3-year old non-assisted bluetooth GPS puck. I paired it with my TPT and got good results. (It takes a few minutes to get a good lock, whereas my aGPS cell phone locks in almost instantly.)

 

aGPS gives faster results and potentially better accuracy than non-aGPS, but from what I can gather, an aGPS device without a network connection should basically become a non-aGPS device. The "a" just assists; it doesn't make the device and is unneeded for a functioning GPS.

 

note: Correction. The wikipedia article sobrado linked to does state: "Some aGPS devices do not have the option of falling back to standalone or autonomous GPS." Including this type of GPS in a tablet would seem silly, though. Besides, sitting outside my window while connected via WiFi does not assist the tablet's GPS. Can anyone confirm the GPS type in the TPT? If there is a hardware limit on this, Lenovo will have to come up with a settlement offer to make all of us non-WWAN tablet owners.

 

In other words, the aGPS on my TPT should work basically the same as my non-aGPS bluetooth puck. Both have access to the same sets of signals. The TPT does not work, though, even after sitting for hours.

 

From my understanding, this is definitely 100% a software and configuration issue.

 

BTW, there are apps that will give you a bluetooth NMEA feed from your phone to your tablet if you don't have a GPS puck. ShareGPS or the widget-based GPS 2 BT (on the phone) might work if paired with the "Bluetooth GPS" app on the tablet. I can confirm that the "Bluetooth GPS" on the TPT does work with my Bluetooth GPS puck (not phone). This is on an unrooted, regular TPT.

Re: OTA2 fix list

I did the OTA 2 update without having the unit on the charger. It worked anyway, and now shows that it's operating the 86US update. My question is, does the battery firmware update still take since it wasn't on the charger when I did it?
