GP-2106 Does not provide NMEA characters

Post by JoeNamat » Mon Jun 15, 2015 2:26 pm

Hi everyone,

I've got a GP-2106 with the associated evaluation board. I connected the board as follow

Code: Select all

NUCLEO L053R8       GP-2106 Eval Board
PC_4  <-------------------  TX
PC_5  --------------------> RX
3.3V  <-------------------> VCC
GND   <-------------------> GND
I just coded a pass-through

Code: Select all

RawSerial gp(PC_4, PC_5);
RawSerial pc(USBTX,USBRX);
int main() {
    while(1) {
        if (gp.readable()){

I then opened Putty on COM4 with 8bNone1 and 9600 bps and press the ON/OFF button of the GP-2106 eval board.
Characters are printed on the terminal at a 1Hz frequency but nothing that looks like NMEA sentences :

My screen is full of ▒ character.

What can go wrong ?
