Empty data in console
Good afternoon @loginov-rocks
I'm trying to run the library with an example for the neo-6m module.
But nothing is output to the serial port.
Please tell me, have you tried running the library with such an ancient and godforsaken module as NEO-6M
?
Perhaps the problem is related to the NEO-6M
module itself, but perhaps also to the version of the UBX
protocol in it ... perhaps the version is outdated, the module shows through the u-center
software 7.03 (45969)
.
First, I configure the module through the u-center at 5 Hz
(tried it at 10 Hz
).
Although according to the datasheet for NEO-6M
up to 1 Hz
is possible and the y-center highlights the field in red, in the binary console
there is a noticeable change in the output speed, but on the module itself the red LED
always blinks with the same frequency - 1 Hz
.
I also disabled all NMEA
and UBX
messages and enabled only three: VEDNED
, POSLLH
, SOL
.
Code, upload to stm32f411
#include <UbxGpsNavPvt.h>
#define BAUDRATE 115200
#define GPS_BAUDRATE 115200
HardwareSerial Serial2(USART2); // PA2(TX2), PA3(RX2)
UbxGpsNavPvt<HardwareSerial> gps(Serial2);
void setup()
{
Serial.begin(BAUDRATE);
gps.begin(GPS_BAUDRATE);
}
void loop()
{
if (gps.ready())
{
Serial.print(datetime);
Serial.print(',');
Serial.print(gps.lon / 10000000.0, 7);
Serial.print(',');
Serial.print(gps.lat / 10000000.0, 7);
Serial.print(',');
Serial.print(gps.height / 1000.0, 3);
Serial.print(',');
Serial.print(gps.gSpeed * 0.0036, 5);
Serial.print(',');
Serial.print(gps.heading / 100000.0, 5);
Serial.print(',');
Serial.print(gps.fixType);
Serial.print(',');
Serial.println(gps.numSV);
}
}
Compile OK
There is peace and quiet in the port ...
None of the existing libraries want to work with this module.
I can only read data from the module using a self-written parser, but the parser has a drawback - it does not work if a delay is added to the parser code, even
10 ms
, and the messages are no longer parsed.
Therefore, I want to make the module work with normal UBX
parsing libraries.
