FOCBOX + HM-10 Bluetooth do I need resistors?

You don’t need the resistor, but you need two cross the RX and TX as @Ackmaniac explain.

You need to connect the Bluetooth module this wayvia the 5V Vesc to VCC Module GND Vesc to GND Module RX Vesc to TX Module TX Vesc to RX Module So you see that RX and TX needs to be crossed.
