Stuck in MetaBoot state
Hi, I was trying to update firmware from 0.6.0 to 0.9.0 without success.
First, I used MetaWear app from Google Play to do the update but error occurred: "Uploading failed: DFU SERVICE NOT FOUND (262)"
After that I stuck at MetaBoot mode and now I can't connect to this device... I was trying to update firmware few times.
Next, I was trying to upload latest (and later also older versions) downloaded from http://releases.mbientlab.com/metawear/vanilla/ using nRF Toolbox - but still no success. Error messages were like these:
- mostly "Uploading failed: DFU SERVICE NOT FOUND (6)",
- few times: "Uploading failed: DFU SERVICE NOT FOUND (262)",
Next, I reset device pressing switch while plugging into usb and by connecting pin 20 with GND and then I was trying to upload firmware to "awake" device from MetaBoot mode but MetaWear device is not working properly.
I'm using Lenovo a3500-h running Android 4.4.2. I don't have other Bluetooth LE device.
What else could I try? What could I missed?
