hi,
we would like to test the detector behavior in higher dose rate levels. I have the detector set to experimental mode (of course) but would like to log the data somehow. We need them for further analyses.

As I know, those data are not saved in Radioactive@home database, so I need probably to catch them during sending or directly from the device.

I was able to identify the device using USB Device Viewer:

Device Descriptor:
bcdUSB: 0x0110
bDeviceClass: 0x00
bDeviceSubClass: 0x00
bDeviceProtocol: 0x00
bMaxPacketSize0: 0x08 (8)
idVendor: 0x04D8 (Microchip Technology Inc.)
idProduct: 0xF6FE
bcdDevice: 0x0301
iManufacturer: 0x01
0x0409: "microchip"
iProduct: 0x02
0x0409: "radioactiveathome.org GRS"
iSerialNumber: 0x00
bNumConfigurations: 0x01

ConnectionStatus: DeviceConnected
Current Config Value: 0x01
Device Bus Speed: Full
Device Address: 0x01
Open Pipes: 1

Endpoint Descriptor:
bEndpointAddress: 0x81 IN
Transfer Type: Interrupt
wMaxPacketSize: 0x0008 (8)
bInterval: 0x64

Configuration Descriptor:
wTotalLength: 0x0022
bNumInterfaces: 0x01
bConfigurationValue: 0x01
iConfiguration: 0x00
bmAttributes: 0x80 (Bus Powered )
MaxPower: 0x32 (100 Ma)

Interface Descriptor:
bInterfaceNumber: 0x00
bAlternateSetting: 0x00
bNumEndpoints: 0x01
bInterfaceClass: 0x03 (HID)
bInterfaceSubClass: 0x00
bInterfaceProtocol: 0x00
iInterface: 0x00

HID Descriptor:
bcdHID: 0x0101
bCountryCode: 0x00
bNumDescriptors: 0x01
bDescriptorType: 0x22
wDescriptorLength: 0x0016

Endpoint Descriptor:
bEndpointAddress: 0x81 IN
Transfer Type: Interrupt
wMaxPacketSize: 0x0008 (8)
bInterval: 0x64


and maybe I would be able to log it using something like SnoopyPro, but would be better if there is a more comfortable approach.

thanks

The data captured in experimental mode is not archived, but it's stored in 'trickle' database, accessible for around 30 days.

EDIT: A quick example, you can find data from your sensor here: http://radioactiveathome.org/boinc/gettrickledata.php?start=0&hostid=6743

The script reports first 5k samples, to get newer samples you have to 'scroll' through the data by providing 'start' argument.
