storing the car for winter, put some improvement for measurement / timing on todos list till next season.
Think it would be great to access the fast progressing GPS tech from UBlox.
NEOs:
M8N 3 concurrent up to 10Hz
M8U 3 concurrent up to 30Hz UDR Solution

Had a M8N Drotek Module on hand and tried the following szenarios:
Szenario 1:
Connecting via usb cable OTG to Samsung Tablet
Result 1:
got access for test/configuration with this app:
https://play.google.com/store/apps/deta ... nter&hl=en
Szenario 2:
connected a HC05 clone from ebay to RX ,TX, VCC,GND of the Drotek Module (swap RX and TX and ignored 3,3V 5V mismatch as always

powered the Drotek Module (and so HC05) via micro USB
searched and installed Bluetooth Device HC-05 on Samsung Tablet
Result 1:
got access for test/configuration with this app:
https://play.google.com/store/apps/deta ... nter&hl=en
(configuration would be also possible in ublox pc tool....)
Result 2:
“set it to 10Hz” with this App:
https://play.google.com/store/apps/deta ... tter&hl=en
Result 3:
got access with different GPS Test Apps by choosing external GPS Bluetooth Device HC-05.

Think its worthwhile because it gives a good solution at low cost and has potential to improve in future with low effort for adoption.
ordered a M9N Module and will post an Update when its arrived and running.
