Sara N211 VSIM Pin?


am I right that there should be 1,8 volts in Sara N211 module when Sara has been enabled (pin 7 high). If it so then i had broken shield from Sodaq.

Hi Tappi,

How did you check the VSIM signal/voltage? The SARA-modules reads/writes the SIM card very quickly (and puts the voltage low after it is done), so you will only be able to catch this with an oscilloscope.

Do you still have issues with your shield?

Hi and thanks for the reply. I measured it with multi-meter. After I have wrote to this forum I found the conversion where this VSIM behavior was described. I still have issue, but I will keep trying.
