R19 is the resistor on the TX path from GPS to CPU -R17 is the resistor for V_BK GPS power (measured 3V - ok!), R20 is the resistor for the RX path from CPU to GPS. R18 for RESET (it is low and GPS reset is high - ok!) * V_BK for the GPS should probably be supplied from something always on * use S113 soft device 7.2.0
