Cannot Transfer Data to from CMS50D or E to SleepyHead - ArthurP - 04-01-2017
Hello All
Summary:
I own both a CMS50D and a CMS50E and am unable to reliably upload recorded data from either of them to SleepyHead. If SleepyHead developers can provide advice on how to debug this problem I'd be glad to contribute financially. Otherwise I will solve it by uploading data to a Windows virtual machine.
Details:
I'm unable to reliably upload recorded data from my CMS50D+ to SleepyHead (ver. v1.0.0-beta-2) running on Mac OS X Yosemite (10.10).
The main problem is that the data does not transfer or only partly transfers. Following the device (from Facelake a few years ago) and SleepyHead instructions, I do and experience the following:
- Connect the pulse oximeter to the Mac via the cable provided. As I wrote above, I've confirmed that this transfers data from the oximeter to the Mac.
- Go to the recording screen on the oximeter. The menu says Alarm, "Recording on", "Exit", and some other things.
- In SleepyHead, click Oximeter -> Oximeter Import Wizard -> Start -> Select device "CMS50D+ ..." -> Import directly from a recording on a device; sometimes SleepyHead crashes at this point.
- Push the white button on the oximeter, which should transfer the data to SleepyHead.
- SleepyHead shows "Oximeter Import Wizard"; I set the time and click "save and finish".
- Little or no data is present.
Give this situation, I plan to install a VM (probably Parallels) and buy and install Windows so I can upload data.
Regards
Arthur
PS. I may not have time to reply to responses, but will try.
Systems:
Macbook running OS X Yosemite 10.10.5
SleepyHead v1.0.0-beta-2, Build Date: Apr 21 2016 11:02:02, Revision: cb213cc (master branch)

o.O do NOT buy Windows just for that - there are plenty of 90 day trials out there directly from MS ... just google for them (even ready-to-mount virtual PCs)

If you haven't installed the UART driver for a Mac, you will need to Google the term "silicon labs cp210x usb to uart bridge driver mac" for obtain the proper driver.

This is not the problem. I've installed the driver. Communications between the CMS50D/Es is confirmed by both real-time data transmission to SleepyHead and partial transmission of recorded data. The bugs are in SleepyHead's code for receiving recorded data. One possibility is that SleepyHead does not handle Macs with multiple cores properly, my computer has 2. Another possibility is that SleepyHead unintentionally relies on delays caused by writing to disk. My computer has a SSD drive, so those disk-write delays are much shorter.
I would write this in a SleepyHead but report, but cannot find a public bug tracker for it.

This is a nice idea, but unfortunately there are no free Windows trials available.
Nor do any of the common Cloud VMs appear to fully support USB forwarding.

one thing I have noticed with my 50f, sometimes it only uploads a few minutes, I need to upload it again to get the full night.

Google "windows 10 enterprise trial", you can download straight from Microsoft the 90 day trial.
In regards to this " One possibility is that SleepyHead does not handle Macs with multiple cores properly, my computer has 2. Another possibility is that SleepyHead unintentionally relies on delays caused by writing to disk. My computer has a SSD drive, so those disk-write delays are much shorter."
SleepyHead requires MacOSX 10.7+, which requires a multicore processor, so I don't believe it is a multi-core problem. I highly doubt it has anything to do with your ssd drive either, but what do I know, you're the "Computer Scientist".

Microsoft has like forever their "please do not just try an illegal copy - try a valid version from us first" mentality
just googling and using the first 2 results comes up with this:
https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/
https://developer.microsoft.com/en-us/windows/downloads/virtual-machines
(they do have plenty more ... personally I don't know of one single microsoft product you can not test first in a ready to use virtual machine ... and I don't know of any company supporting that many different types of virtualiziers^^)
