CONFIG_NRF_MODEM_LIB_SENDMSG_BUF_SIZE

Size of the sendmsg intermediate buffer

Type: int

Help

Size of an intermediate buffer used by `sendmsg` to repack data and
therefore limit the number of `sendto` calls. The buffer is created
in a static memory, so it does not impact stack/heap usage. In case
the repacked message would not fit into the buffer, `sendmsg` sends
each message part separately.
