control on board LED?

How do you control the on board LED in Arduino?

How do you change it from solid green to flashing if GSM signal present?

Thanks

Hi,

  • These is the RGB LED control example : …\Arduino_IDE_for_RePhone\workspace\rgb_led_test.
  • You can use api " vm_gsm_cell_get_current_cell_info" in file “vmgsm_cell.h” to detect the GSM signal.
