Has there been a version of the MetawearApiT,,, app released that specifically differentiates between the (No name) situation and displaying "Metawear" by default or at least refreshing the name periodically? It's frustrating having to switch to the…

Any news?

I've done some more testing and it appears to be a problem with Apple's Bluetooth LE. When scanning from a PC (using my own App) I always see the name set in the macro. However, when using your software and a third-party LE App both on Apple iPhone …

Having tried the 1.3.7 firmware, it appears to have addressed the 300uA posted originally. I am aslo not seeing the Intesity issue when setting Intensity 15 for the LED, the current seems to be stable around 700uA. I'm using the color Green for my t…

Alright, well this question was prompted by an apparent loss of the flashed macro. Some MetamotionC devices that are being programmed with a startup macro to change the advertised name seem to operate correctly for some time (days) and then apparent…

A little more information regarding anomylous LED behaviour. Using LED patterns with rise/fall time of 0ms, a high of 10 seconds and a duration of 20 seconds at 31 for intensity, current consumption is steady around 1.2-1.3mA for Green and Blue and …

Tried some of the older C-Pro devices that we're just sitting idle and as shipped (since they didn't support the newer Sensor Fusion being used in the Metamotion). Was able to reliably wake one of these up. Was going to send this and some of the Met…

Here are the links to some videos (hopefully in the correct order). It's riveting stuff. Video 1 Video 2 Video 3 Video 4 Video 5 Video 6 Video 7

Give them a shake, turn the over and over a few times, pick them up, put them down, take your pick. I moved 44, one at a time and then rescan for any that have awakened since the number that do is inconsistent, so it takes that amount of time for 18…

Alright, lets read from the same book and the same page. I reflashed 44 of the Metawear devices (firmware 1.3.6, they already had it but just to be sure). I then used the sleep function in the Metabase software (your software [Apple IOS]) to put the…
-
In answer to your question; macroWritten simply sends a command to turn on the LED as a visual indication that the operation is complete. The 'sleep' code is triggered by a separate ui-button in the program. Don't confuse the stated problem with the…
-
As you can see, the commands being used are very straight forward. The Macro for changing the name works as was mentioned in my previous thread and the sleep process is a two step command so isn't that complicated. Can you please let me know what re…

Eric. I'll see what I can do about a video. The test procedure per device takes several minutes to turn around so it's a time consuming process to demonstrate waiting for a unit to awaken, but in a nutshell, the test procedure is as follows: Flash …
-
Eric, I thought I might add that after retesting some of the units that hadn't awoken from movement, some that previously hadn't now do. I would also add, that these units were programed with a Macro that changed the name they advertised. This had r…

35 of 130 units tested. There are an additional 80 which remain untested. They've been purchased in batches over the last three to four months.

Eric, it appears to be the Creator's Edition that is at fault. Microsoft have apparently overhauled the Bluetooth services and many people have complained that subscribing to a BTLE characteristic fails to return data. There have apparently been a n…
-
Thanks Eric, the Macro worked a treat!
-
Well, yes you lose connection AND the device no longer advertises.
-
Eric. I've tried writing the app using the code snippet provided above and I am using another MetaMotionC device (in case there was some problem with the first). After executing the code Bluetooth reports that the device looses connection, so from t…
-
I have done some additional testing and it definately appears to be the ambient light sensor. A bright LED light directed at the board causes the current draw to increase greatly. Issuing the 'stop' command to the Ambient Light sensor through the C+…
-
Eric. The device does reach reset. As I am monitoring the power consumption I can see the behavior of the device, and it is as it is when it resets. Is there any condition under which after sending the command to sleep, that the sleep mode would be …
-
Eric. This is one of the techniques I tried. I gave it another shot putting a 1 second delay between the commands. Out of 2 dozen attempts to put it to sleep, it succeeded once where the device reset and sat at about 14 uA consumption. Pushing the b…
-
Eric. I've tried using the enablePowersave function from the Android API. It sends the byte sequence 0xFE 0x07 to the device. I've then followed that up with the 1) mbl_mw_debug_reset command, 2) the mbl_mw_debug_reset_after_gc and 3) removing / ins…
-
Ok. Today I was sitting performing some current tests while trying to 'sleep' the device. The current was a steady 17.6 uA (between advertisments) which is within you stated spec for firmware for 1.3.5. Now the only difference between today and last…
-
Matt, having tested a number of units on firmware 1.3.5, multiple times (connect/disconnect), this is the method I'm using and results I am seeing. I connect a device to it's battery (CR2032) through the multimeter. The reading for several seconds …
-
Oh, and out of curiosity, what is the power consumption when in sleep mode?
-
By reseting I assume you mean, remove and insert the battery, or is there a command that can get the board to reboot?
-
Updating to firmware 1.3.5 hasn't produced any recognizable change in the results I am seeing.
-
Matt, just an FYI; our testing area is at least 6' from an AC power source. The multimeter itself is battery powered. There is also overhead fluorescent lighting. But if it will be addressed by a firmware update, that'll be awesome. Any idea how lon…
