Neo6mV2 + Nrf24l01 Gps data transmitting problem

Using Arduino Networking, Protocols, and Devices
#1

Hi guys, I am trying to send some sensor data with a gps longtitude&latitude info. I can send the sensor’s data but when I try to add GPS data, It sends only “1” time then serial monitor and program freeze. I’m using 2 arduino nanos + 2 nrf24l01 here are the codes and the screenshot where it is freezes.(Sorry for bad English pls help)

You need to have identical structs for the sender and the receiver.

If that does not solve the problem go back to a very simple pair of programs that does nothing but transmit and receive data - leave out everything else. Get the simple program working and then add back the other stuff piece by piece testing at every stage.

* Indent your code. Press control-T in the IDE editor to auto-format your code.

* Don’t use delay. You will lose GPS data.

* Link to the libraries you are using. There are many versions of DHT11 and RF24.

* Don’t include <printf.h>.

* Don’t do this:

    float c = -999;
    c = compass.read();

Just do this:

    float c = compass.read();

* Put the GPS on pins 8 & 9 and use AltSoftSerial instead of SoftwareSerial, or use NeoSWSerial on any two pins.

* Look at the NeoGPS Troubleshooting page to understand why you shouldn’t use delay or print too much.

I have attached a version of your sketch, modified to use NeoGPS and NeoSWSerial. If you want to try it, NeoGPS and NeoSWSerial are available from the Arduino IDE Library Manager, under the menu Sketch → Include Library → Manage Libraries. It saves about 150 bytes of RAM.

Based on information in your other thread, this is almost certainly a power problem.

You should try NMEAorder.ino to make sure your LAST_SENTENCE is configured correctly. This would not cause it to freeze, though. I'm glad you figured out how to enable HDOP... I'm sorry I forgot to mention that. :confused:

#8

-dev, I think this is a completely different problem because in this one there is a problem with no-antenna NRF but the other thread you mentioned, I deleted my gps code, only sensor data is transmitting and with little NRF there is no problem at all. So short story I don't think it is connected but very respect to your interest man thank you.

#9

The last print before it freezes is "Simdi Gonderliyor - ". This is just before the radio.write. If adding code makes it freeze, it could be a memory corruption issue. Please provide links to the libraries you are using. I could not get your code to compile with the RF24 and DHT11 libraries I have.

The freeze can also be caused by poor I2C wiring. The I2C Wire library can freeze if it misses one of the bytes sent by a sensor. It could be the wrong resistor value or noise caused by the wires (too long?). Transmitting may cause enough noise to affect the I2C wires, either from interference or power supply issues.

Please show a schematic and picture of your modules. Many problems have been found quickly by looking at these two important items.

For example, did you level-shift the 5V Arduino signals to/from the 3.3V ublox device? Read more about it here.

Did you try NMEAorder.ino to check the config?

Try commenting out the radio code (setup, write and read). If the sensors and GPS work ok, then you know it has something to do with the radio.

Next try just doing radio setup and read (no transmit). If that works ok, then you know it has something to do with radio transmitting.
