BME Replacement
 

Am testing Pali's bme replacement. Does the job, led's flashing etc. The only thing is that the led never goes green and the status area icon keeps pulsing. Battery has good charge by then, and is perhaps full by any standard.

Have read k-p threads where bme replacement is mentioned. Rather than posting reams of perhaps wrong output here (e.g. hal-device bme), I would be gratfeul if Pali could specify what he might need. Or is no green led normal?

Thanks.

Methinks BME-replacement does need its own thread.

How sad, I must correct myself. I got a green led during the last charge. Thing is, this time I forgot the phone and hours later there it was green.

It appears that "bme replacement" has a different charging "profile" to "bme stock" and takes longer to produce the green. I use "bnf" and am content frankly at anything 95% or so. Less of course is better for the battery.

Further testing. Rebooted with wall-charger attached. Booted up properly. Connected wireless and ran sshd. Connected as root via ssh.

Disconnected wall-charger and then reconnected. Received message that device drawing more power than being provided. Via ssh ran :
Detecting wrong charger type. That may explain the differing charging profiles.

How to revert back to stock bme?

Re: BME Replacement
 

I have a similar problem, but my cell phone had some circuit in the device. The cell I bouht was used and was defected. Previously, I had problems with restarts after shutdown, then with running it properly.
I installed these four packages and after a reboot my cell indicates the charging procces by the status area and by pulsing of the yellow LED.
After charging the battery and disconnecting the charger it still shows me loading and the LED stays constantly green.
When the cell is switched off, the device receives 0.35A (350mA) from battery.

What's the problem?
Can this be checked diagnostically?

Re: BME Replacement
 

I am encountering a bug that causes the status-area-applet show constantly 50% charge. If I charge the battery full overnight and still keep the charger connected I get full battery, but the second I disconnect the charger the bar drops to 50%.

The readout of the bq27200.sh (with the -f):
Readout of hal-device bme:
installed versions:
Otherwise the bme seems to work normally.

Re: BME Replacement
 

You can downgroad it to stock bme version:

Re: BME Replacement
 

This morning, different behavior. After full night connected to charger, green led as usually. But after disconnecting the charger green led stays on and is lit every time screen is turned of. Below the readouts from hal-device bme after disconnecting the charger.

After two hours of idle in the pocket and one phonecall the green led is still on and the battery icon shows full. If I keep the screen on for a while the battery icon drops to 50%, but with screen off for while it returns to 100%. Hal-device bme readout and bq27200.sh at this point.

As the green led is still on I connect the charger again and it starts charging and pulsing yellow led. After a while, before battery full level is reached I disconnect the charger and led goes out as normal.

If you dont count the strange led behavior the phone feels like its working normally. I'll keep testing the new bme.

Re: BME Replacement
 

I can confirm this but do not know under what circumstances it happens. Many times it works fine.

Re: BME Replacement
 

What about N9/N950 target ? could an open BME replacement fit in nemomobile ?

Re: BME Replacement
 

is this bme installed with the PK? Does it fix the issue of the battery randomly dropping off to 4%?

Re: BME Replacement
 

I dont think this bme solves any other problems directly than the fact that Nokia BME is closed source blob and Palis BME is not. It may ofcourse be better in many ways, I think the main purpose of this is to replace the closed source version and thus enable better compatibility with current and future applications.

Re: BME Replacement
 

for me it seems to of fixed it

Re: BME Replacement
 

Ok, I can add one more bug to report. Regardless of the current battery level (100% or 50%) after a while of moderate use like web surfing and for example reading mail, the battery level drops to red and the phone sounds the low battery alarm and notification banner tells me that the battery level is low. This does not affect the usage of the phone in any way and the autoshutdown does not kick in. After the work is done, and I put the phone on idle the battery level rises back to 50% or 100%, where it was before moderate usage.

I got tired of the low battery alarm so yesterday I decided to replace the new bme with the stock one and confirm that the 100%-50% battery level and the low battery alarm was connected to the new bme. I installed the stock BME with this line:

After hitting the reboot button, phone went of, but didn't reboot. I couldnt get the phone to boot or to charge. I swapped a full extra battery inside and the phone then responded to power button and booted up. The battery icon was 100% and the green led was on on when the screen was off (normally even with "full"battery after the boot, my phone show one level lower than the full battery). I then concluded that the batterylevel problem had something to do with the bme-helper files and not the bme itself, so I reverted them also back to stock:

And everything went back to normal. Have to see in the future to test only the BME replacement, if it works without the other new files.

Re: BME Replacement
 

I think I know at least one situation when this happens. And this observation also relates to the posts with which I opened this thread.

With bme replacement (how was it before???), my n900 is quite sensitive to a partial-contact made whilst (ever so carefully) inserting the wall-charger connector.

With usb mode installed one can readily see this. If you make a "hesitant" contact, usb mode will display to request mode selection. The device will charge but in fact thinks it is connected via usb and not the charger. This likely happens because the hesitant (partial-) contact does not register the expected current and so defaults to the lower.

I get the persistent green light when the charge completes under this scenario. Don't know if it always happens however. So far, the persistent green led has not occurred when the wall charger was seen at the start or when I used usb mode to set the mode as "usb peripheral mode" after a partial-contact connection was made (whereupon the n900 sees the wall-charger).

Re: BME Replacement
 

I'm wondering, has the situation with the BME-replacement gone forward, as the CSSU-Testing now has new status-area-applet for the battery? I think there is also something going on on the backroung that us mere mortals are not fully aware as a custom version of the older applet is mentioned in Estels post.

Has anyone used the BME-replacement with the new applet and how it works?

Re: BME Replacement
 

I am on thumb/testing and have bme replacement. I love the battery applet as it gives the proper info but of course the calibration must be there.

Looks as such:
Battery: xx%
xxxx/1502 mAh xxhours/ x days

Re: BME Replacement
 

This is very irritating for people using dual-cell batteries and charging with higher currents (1250 mA), as it limits charging to <500 mA, resulting in getting less-than-half-charged device, after usual "full charging" time passes. Not to mention that device "thinks" it's connected as USB client indefinitely, even after you unplug charger.

One can workaround it without rebooting device, by (ab)using hostmode applet - just select mode "peripheral with charging (it doesn't matter that you're in this mode already), then, issuing (as root):
...then plugging and unplugging charger, then issuing above command again, and finally, connecting charger back. At this point, it should charge as it should (in my case, full 1250 mA), without any illusion of being connected in USB data mode, nor side effects. Sometimes it need to repeat those steps 2 or 3 times, but will eventually get unstuck.

As you have seen in my post from CSSU thread, new version of applet may be PITA, in case it decides to use "design capacity" as "full". I always end up with nonsenses like 3300 current mAh, 1200 mAh max. Also, as shadowjk noted, even for people with "regular" batteries, it (percents, current charge, max charge) doesn't add up arithmetically, if you spend a minute and calculate it by hand.

Solution - modify one line in applet's source code, to make it use bq27x00_battery reported capacity with precedence over rx51_battery/bme reported max capacity, as the latter is plain BS. For kernel-power users (everyone and his uncle) it will work OK, for non-kp users, it will work just like to does now (aka report idiotic values, but still looking pretty, in case of regular batteries).

/Estel

// Edit

I hope CSSU guys will fix it or did so already - if it won't get fixed "upstream", I'll bloody do that one liner, and upload fork to extras-*. It would be, well, silly situation, but Meh.

Re: BME Replacement
 

I've just installed the replacement and the mass storage popup appears after a long time. Any ideas why?

/edit: sometimes the popup appears after sliding out the keyboard, sometimes doesn't appear at all.

Re: BME Replacement
 

hi to all
I'm testing the BME replacing from Pali. Great work!
But I have a BIG problem. I use a wall charger with 4 batteries. So when I change a battery the one I insert is not calibrated and I have 0/0.
Can I revert to original or old or CSSU BME? If I try to use the stok one (the link given above) it says is not existing

Thanks in advance

Re: BME Replacement
 

It's been several times. BME replacment reports battery low at ~400 mAh, turns of at ~300 mAh. And after reporting, the device shuts down so quickly that there's no time to even plug it into the wall charger. Any ideas how to fix it?
