Hi Gordon,

I currently deal with signal of acc and gyro for motion detect. Some features might require highly sampling rate to accomplish. Therefore, a rechargeable Puck might be the best implementation for clients in several scenario. It is fine so far as I kept the features in development. I'm looking forward to the nRF52840-based device!

Cheers

Hi Espruino Team,

I'm working on the development based on Puck.js v2.
And I'm pretty satisfied with the hardware spec and development environment.
However, many of my clients are asking for the rechargeable feature of the device.
So I'm curious that will the rechargeable battery spec (maybe Puck.js v3, v4, or.... ) be released in the future?
Or if there has an existing spec relevantly similar to Puck.js v2?

Best regards

Hi Gordon,

Thank you for your reply. I think that I will go through with the method I mentioned. And keep looking forward to your solutions. Thanks again :)

Hi Gordon,

Currently, I use negative value of z component for adjusting this problem. Might the problem be fixed in the firmware for the future release?

Best regards

Hi Gordon,

Always nice to hear from you. :)
I've downloaded 2v07.33 and upgraded to my Puck. The bug has been eliminated.
Thank you for your fix quickly.

Best regards

Hi all,

I have experienced the bug while calling Puck.getBatteryPercentage() and NRF.getBattery() in firmware v2.07, the values were 0 and -3.6, respectively. It is OK while I downgrade to v2.06. These wrong values existed only if I send my code (for my own server and service) to RAM (using Web IDE). I've tested two Puck.js devices I have. Just report the issue for the reference. Thank you all my lovely Espruino team.

Best regards

Hi All,

According to the description on page 18/115 of the "LSM6DS3TR-C.pdf", the x, y, z axis is following the principle of right-hand rule.
However, I just used

Puck.accel()

to get the corresponding acceleration values along the x,y,z axis to test 6 static poses of puck.js, i.e., +x, -x, +y, -y, +z, -z axis along with gravity direction. I got the coordinate system illustrated in the attached figure. This is not followed the right-hand rule. Is there something I missed?

Hi Gordon,

After my tests, it might be caused by my Bluetooth dongle. My puck has no problem to connect with other bluetooth-embedded notebooks and computer. Thank you again for your kindly reply.

Best regards

Hi Gordon,

Nice to hear from you. My computer is a desktop with Windows 10 enterprise installed. I have a bluetooth 5.0 dongle connected to my computer.
Yes, I have tried Web IDE via Android Chrome (but not the IDE relay), and it was connected successfully.
I will have other tests to exam whether if the trouble comes from my dongle.
Anyway, thank you for your reply. :)

Best regards.

Hi all,

I cannot connect to Puck (firmware: 2.06) with Web IDE.
But I can connect to my Puck.js using nRF connect APP (android) and Droidscript Plugin and also my BLE-based web app.
The IDE can search successfully my puck, but after connecting procedure the IDE log print out "Disconnected from Web Bluetooth, Puck.js xxxx". I have rarely few times to successfully connect to puck, but IDE disconnected to puck after minutes.
I've tried to reset, hard reset, update firmware.

Best regards
