and then the board enters Bluetooth mode

You can ignore and forget about them and the SRF10 will work fine

The rest point (sometimes called neutral position) is set to 1

5V, 3.4A Step-Down Voltage Regulator D30V30F5 Brushless Motors *Peak Current: 110mAThis small synchronous switching step down (or buck) regulator takes an input voltage of up to 45 V and efficiently reduces it to 5 V. The board measures only 0. 7 0. 8 yet delivers typical maximum continuous output currents between 3 A and 4 A , depending on the input voltage. An optional enable input can put the regulator in a low power state with a current draw of 10 A to 20 A per volt on VIN. The regulator also features reverse voltage protection
