I want to make GPS logger with arduino + GPS + SD shield. I found old GPS bluetooth device that work.
In first phase I want to get on serial monitor GPS data.
Can someone tell me how can I find or to point where is pin on GPS that I need to connect to TX, RX on arduino.
I tried but ... no success.
I always get garbage.
I attach picture of GPS module.
First step would be to find and identify the Bluetooth chip. Get the datasheet for it to see how it gets data from the GPS. If it's a standard serial connection then that's where you tap in.
It is AIRLogic Bluetooth
ABM-200-2xxx
I found datasheet.
Physical interface to host (UART, USB).
Specification
-Operating Conditions
Support Voltage………..…... 2.7V ~3.6V
Temperature Range….…..… -20~+70°C
-Power Consumption
ACL Data (UART/115.2kbps) ……. 18mA
Voice Only (HV3 Packet) ………… 28mA
-Radio Characteristics
Receiver Sensitivity … -84dBm
Transmitter Power ….. +2.0dBm(Typical)
What now?

We hope that the GPS module doesn't implement USB so all you have to do is determine which pins of the Bluetooth chip are the UART (serial) pins. Connect those pins to your Arduino serial (or SoftwareSerial) pins. Start with the Bluetooth chip default baud rate.
