I am trying to log data from a GNSS receiver through the SerialX port. the sketch I am using is the example "Example5_Customserial" from the Sparkfun u-blox GNSS v3 library. The Arduino Giga cannot parse any data from the receiver saying it is not connected. I have already tried the same example fro…

after reading a bit about the Giga, it seems that Serial.begin(); is reserved for USB communication and not using one of the UART and the HardwareSerial objects are as follows: Serial1 -> TX0/RX0 (D1, D0) Serial2 -> TX1/RX1 (D18,D19) Serial3 -> TX2/RX2 (D16,D17) Serial4 -> TX3/RX3 (D14,D15) ➜ so …

[image] the_marox666: and supplying pin did you connect the GNDs?

Yes, even if it should be a common ground

It looks like a too much contradicted settings about GNSS serial: [image] the_marox666: #define mySerial Serial1 mySerial.begin(38400); myGNSS.connectedToUART2(); while (myGNSS.begin(mySerial) == false) Is UART2 and Serial1 are the same on Giga?

just reading from the code's comments [image] the_marox666: myGNSS.connectedToUART2(); // This tells the library we are connecting to UART2 so it uses the correct configuration keys and what you said [image] the_marox666: I connected: TX to Giga pin 19 (RX1) RX to Giga pin 18 (TX1) …

Uart2 is the communication port on the GNSS chip, not on Arduino, which correspond on tx and rx on the chip [image]

I have just done some tests with the Giga, the Mega and an oscilloscope. On Mega, the library works flawlessly and with an oscilloscope, I can see that the board can receive and send data. Before the GNSS board starts streaming data needs a prompt from the Arduino Board when the code reaches the lin…

It is quite possible that the library is simply not adapted to Giga. I see inside the code there are conditional compilation directives for different types of Arduino, the Arduino Giga is not there.

OK I don't know enough about that module then

(does your module support UART2 ? is it the right one? have you tried without calling this?)
