nrf_socket og nrf_close

[Tron]

When I have opened a nrf socket with nrf_socket to extract GPS data, when the GPS acquisition phase is over, I want to close the socket, since I'm turning the GPS off. calling nrfclose with the socket handle as input parameter,, returns -1, normally an indication that somthing has gone wrong. When I try to reopen the socket again, the open socket command also fails. Please advice on how to proceed.

I see that you are calling close() instead of nrf_close(). Have you tried using nrf_close() instead?

Yes, of course . This is a snippet of the code at that point in time. Which socket options do I need to set in order to be able to reuse the socket? THis might be the cause of my troubles.

I found out, first, I needed to set a socket option: 

nrf_setsockopt(fd,NRF_SOL_GNSS, NRF_SO_GNSS_USE_CASE, &first,sizeof(uint8_t));

where first is 1 if this is the first time the socket is created, otherwise 0

THen, before close, i needed to set 

nrf_setsockopt(fd,NRF_SOL_GNSS,NRF_SO_GNSS_STOP,NULL,0);

before I did an nrf_close
