That's some awesome information. Is this something that you maintain seperate from Robert's Info? (Sorry If I'm off topic) I'd like to start one for the Florida Markets (As I don't see one there for Florida) or if there is maybe you could point me in the right direction. Would like to contribute information to the group as much as I can. :-D Any input would be appreciated, and you may PM me if you like. Or I can move to a different thread.

 

I'll PM you the info.. I have a template already since several other markets have also used it; Utah, Cen Iowa, Columbus, West IA, East IA, etc.

Hey Mike,

If you're taking feature requests, any chance of adding a "chime" for when loosing 800/LTE? Thanks!!

Patience is a virtue. :D

I'm always taking feature requests!  Both of those were already on the list, and it's in the latest beta that my minions have been testing out for me (see http://www.bluelinepc.com/signalcheck/change-log/ for a preview).

 

I've been crazy-busy lately, but I have been sneaking a few minutes here and there to polish off an update.. it's coming soon.. maybe very soon..  :ninja:

I still can't believe signalcheck works so well on my ancient (non-4g) LG Optimus S!!  I have seen Android stop allowing signalcheck to update but I've noticed the LG Debug screen must somehow bypass Android as it ALWAYS shows the exact cell info in real time.  I sure hope you have logging of some sort in your new update which I noticed on your website was one of the requests.  Maybe just let us view the "cache" file of site street addresses which knows if a site has been looked up on the internet before because it displays the site address in lower case.

I'm sure this question was asked 1000 times but when can we expect the signal check pro app to notify us if we are connected to lte 800 and 2600? *I know we need a triband phone*

 

It's something very high on my priority list.. but until we have some tri-band phones and networks to test on, it's hard to make any progress.  I think many Sprint geeks (certainly the S4GRU) would love to be able to monitor which band they are connected to.  Unfortunately, the folks with the first few G2's are having so many LTE issues right now that I'm not going to rely on any of them just yet.

 

There are no built-in Android routines to get band info (LTE or otherwise), so unless Sprint does something to identify the different bands on their end (as they did with the 22xxx BIDs for 1X 800), I'm going to have to hope I can come up with something by digging through source code and implementing manufacturer-specific (if not device-specific) code.  That will not be fun.  I believe I heard that the tri-band hotspots are seeing a different MCC/MNC when connecting to Band 41, so things might work out.

 

I wish there was a universal Android routine that would grab the frequency information, so this would work on any device, on any carrier.. but there isn't.

 

Theoretically, HTC devices should show the connected frequencies as they do now.. unless HTC changes something behind the scenes when they release their first tri-band device.

When you say "stop allowing SignalCheck to update", what do you mean?  The app stops working?  What happens if you exit the app and go back in?  Or is it just the icons stop updating?  Android handles memory management itself, so if it thinks it needs more memory for something, it will kill off older processes it thinks are less important.  This could certainly cause the SignalCheck background service to get killed, especially on older or lower-end devices with less memory to spare.  Going back into the app should kickstart everything again.

 

No logging ready to be released just yet; like I have said before, I prefer to get existing features running better before adding new ones.  Being able to view/edit/clear the cache file is something I've had on my mind as well.

Is it the PLMN?

 

<edited out screenshot>

 

PLMN: 311870

Current Radio Band: LTE B41

 

This is very cool.. I knew I saw a screenshot like this somewhere, I just didn't realize it was right here!  That's showing your MCC/MNC.. often referred to as PLMN, although that's not 100% correct.  Technically, the PLMN is generated by doing math to the MCC and MNC, not just pushing them together.. but I see that a lot.

 

Going to slide this nice little bit of info into the next SignalCheck update, and see if anybody sees it pop up..

Anybody adb android savvy with a g2? Could you pull the Apn file from their device? It holds all the info for connecting to 41 and 26. The mcc and mnc are in that file.

 

Run in the command prop with adb in the path

adb pull /system/etc/apn-conf.xml

That screen was from a Zing btw. I didn't know if you saw that or not.

Yep, I saw that.. but as long as it was a Zing connected to Sprint, it should be helpful. How about this -- next time its connected to old school Band 25 LTE, can you note what the PLMN field displays? See if its 310120..

I was only borrowing the Zing for a few weeks. No longer have it. The PLMN ID on shots from the HTC One I am using is 310120 on B25 and B41 on the Zing was 311870.

It will be 310-120.  All Sprint band 25 LTE 1900 deployment thus far uses that MCC-MNC.  In Denver, Robert encountered band 41 TD-LTE 2600 under 311-490.

 

Below is the expected pool of MCC-MNCs:

 

310-120 Sprintcom

311-490 Sprintcom

311-870 Sprintcom
311-880 Sprintcom
311-940 Clearwire

316-010 Nextel

Actually I forgot i saved all of these on my phone. Here's B25 from the Zing.

Thanks AJ, that is what I expected.. but in the slight chance the Sprint put hotspots on a different MCC/MNC for some reason, I just wanted to confirm. I have the same list already in the database. Thanks for the heads up about Robert's experience, hadn't seen that.

As far as what the network broadcasts, there should be only one MCC-MNC per site.  And that is what we see on the engineering screens.  So, there should be no difference between handsets and mobile hotspots if both are on the same band.  But from what I understand, the UEs themselves may use a different MCC-MNC.  I read that in regard to VZW -- one MCC-MNC for the network, another MCC-MNC for the UEs.  The purpose of that?  I have no idea.  I do not understand why the UEs (or, more accurately, their SIM cards) need to be assigned an MCC-MNC.

Airraives broadcast the same mcc-mnc's as a tower right? I ask because Verizon recently started using different mcc-mnc when connected to their network extenders. I hope sprint doesn't do the same... Some code in Android aosp had to be changed because of this and it caused a bit of a headache.

No, an MCC-MNC has nothing to do with CDMA1X nor EV-DO.

The SignalCheck app is still running and the icons in the task bar still accurately show the signal levels.  Exiting the app and restarting it make no difference.  The SITE INFO (Base ID, Street Address, etc.) stops updating.  Memory isn't an issue as I have learned how the kooky memory management feature of Android works.  That is why I shut the phone off and turn it on when I am going to be taking a drive and monitoring sites without loading any other apps.  And it isn't the app "falling asleep" either as I use the SignalCheck feature to not let the screen go off when the app is in the foreground.

 

This same phenomenon does exactly the same thing when using CDMA Field Test Drive, another site monitoring app.  That program does do logging and after 10 or 15 minutes of no updates they suddenly begin again.....just like SignalCheck.  Since the LG debug screen doesn't suffer from the lapse in updating, I can only assume it is Android refusing to update the app.

    • Since this is kind of the general chat thread, I have to share this humorous story (at least it is to me): Since around February/March of this year, my S22U has been an absolute pain to charge. USB-C cables would immediately fall out and it progressively got worse and worse until it often took me a number of minutes to get the angle of the cable juuuussst right to get charging to occur at all (not exaggerating). The connection was so weak that even walking heavily could cause the cable to disconnect. I tried cleaning out the port with a stable, a paperclip, etc. Some dust/lint/dirt came out but the connection didn't improve one bit. Needless to say, this was a MONSTER headache and had me hating this phone. I just didn't have the finances right now for a replacement.  Which brings us to the night before last. I am angry as hell because I had spent five minutes trying to get this phone to charge and failed. I am looking in the port and I notice it doesn't look right. The walls look rough and, using a staple, the back and walls feel REALLY rough and very hard. I get some lint/dust out with the staple and it improves charging in the sense I can get it to charge but it doesn't remove any of the hard stuff. It's late and it's charging, so that's enough for now. I decide it's time to see if that hard stuff is part of the connector or not. More aggressive methods are needed! I work in a biochem lab and we have a lot of different sizes of disposable needles available. So, yesterday morning, while in the lab I grab a few different sizes of needles between 26AWG and 31 AWG. When I got home, I got to work and start probing the connector with the 26 AWG and 31 AWG needle. The stuff feels extremely hard, almost like it was part of the connector, but a bit does break off. Under examination of the bit, it's almost sandy with dust/lint embedded in it. It's not part of the connector but instead some sort of rock-hard crap! That's when I remember that I had done some rock hounding at the end of last year and in January. This involved lots of digging in very sandy/dusty soils; soils which bare more than a passing resemblance to the crap in the connector. We have our answer, this debris is basically compacted/cemented rock dust. Over time, moisture in the area combined with the compression from inserting the USB-C connector had turned it into cement. I start going nuts chiseling away at it with the 26 AWG needle. After about 5-10 minutes of constant chiseling and scraping with the 26AWG and 31AWG needles, I see the first signs of metal at the back of the connector. So it is metal around the outsides! Another 5 minutes of work and I have scraped away pretty much all of the crap in the connector. A few finishing passes with the 31AWG needle, a blast of compressed air, and it is time to see if this helped any. I plug my regular USB-C cable and holy crap it clicks into place; it hasn't done that since February! I pick up the phone and the cable has actually latched! The connector works pretty much like it did over a year ago, it's almost like having a brand new phone!
    • That's odd, they are usually almost lock step with TMO. I forgot to mention this also includes the September Security Update.
