hello 
Im having problems with MagArrow II data recording, and i'd love some help or advice.
The issue definatly is a problem with the SD connection. Im having no troble connecting to the sensor's WIFI, but when heading to the "Data" page I get the massage "Unable to load servays. Verify that the SD card is insrted correctly. [...]" Indeed in systemtest page i get a "SD card: Failed" test.
Im aware of the SD's spring load mechanism, and tried many times in different configurations, including trying with different SD cards, updating the MagArrow software, but to no avail. The system just wont recognise any SD 🙁
Anyone had a similare problem? Any tips or suggestions?
I'd love to get the sensor working again

I assume you can feel the spring when you insert the micro-SD card. Did you try to format your micro-SD to exFAT?
The other thing I can think of is somehow there is dirt stuck inside the SD socket. Maybe try to blow the socket with air.

@rzhang
Thanks for the reply!
Yes, I feel the spring, and remember the sensor was working a cuple months ago...
I just tried to gently clean the SD socket, and also formated the SD - the MagArrow still doesnt seem to recognize any SD 😥
I can't think of any past sensor usage that may be related to this...
Im at a loss, anyone has more wisdom on the subject?
