  1. Hi, is this USB design has both GPS and GSM capability? If I want to interact with the 2 modules upon plugin, how could I do that?

    Thanks,

  2. You can use software switch. Now i use STM32 based devices - so 2 COM port for host for GPS and GSM.

  3. How do I detect this device on my pc. Thank U

  4. Great site!
