Get GPS sentence through UART (Zephyr)

Hello Oli,

But the other problem that I am getting is when the character that is read is "," the uart_poll_in returns -1 and does not get the succeeding data. Have you encountered this problem? 

return value -1 means that the UART input buffer was empty. How do you know that it is character “,” and does it work with other ones?

Regards,

Markus

Hi Markus, 

I just need to follow up on what you said that Zephyr does not support the Fanstel? Maybe I missed something.

But Zephyr does not support the Fanstel BT840X and for receiving GPS data, you need an external device like the nRF9160 anyway.

For the poll function, I think the program that I have used does not clear the buffer that is why the "," is still read even though the return value is -1. 

I have another question though, can the polling function recognize a space? or when it sees a blank space it terminates the polling? 

Thanks, 

Oli
