NRF9160 BSD socket "send function" isn't blocked.

[Meni]

I use BSD socket to send and receive messages to a TCP server over LTE network.

When I send multiple messages by using send() (with flags = 0) function, I get an EINPROGRESS error.
It seems that send() function is not blocked.

I'm currently using the v1.1.0 release.

How can I fix this problem?

Thank you for the test code.

I was able to reproduce this, and it seems to only manifest itself when filling up the buffer to 4k in bsdlib, where you have to try again until that packet has been free'd from the buffer. Changing the MIN to any number lower than 4096 bytes, for instance 4095 bytes, then it does not return EINPROGESS.

I have reported this internally as a bug.

 

Kind regards,

Håkon

I think we just bumped into this issue but we're running on NCS v1.2 and BSDLIB 0.6.2 (slightly non-standard combination).  Was this bug fixed in any particular version of NCS or BSDLIB?

It was tested on ncs v1.3.0, which would mean bsdlib 0.7.3 was used. it was not reproducible at our end with this version. It is suspected that the rewrite in 0.7.0 (changelog here) fixed this issue.

 

Kind regards,
