Not all customers are OK with having a Bluetooth radio on their gate. For customers who prohibit wireless capabilities the Bluetooth on SmartCNX can be disabled in hardware.
There is a jumper on a pin header in the OXI receiver port. To enable the radio the jumper must be on the left and center pin. Move the jumper to the right and center pins to disable Bluetooth (or just discard it). This removes the power to the radio chip.
