Remote Command Mode

Our kcSerial firmware offers a very powerful Remote Command Mode that can eliminate the need for an embedded microprocessor on the remote device. Any Bluetooth device using Serial Port Profile can put our kcSerial device into Remote Command Mode. This is like a remote terminal, where the kcSerial device can now receive its AT Commands wirelessly. So, a standard Bluetooth device can now make the remote kcSerial device read, write, and configure its remote IO pins.
