Hi Mikko,

Hope you are doing good.
we referred below link for sending keep alive message periodically to keep the connection alive in ANSI C library. found that cl_keepAlive function is missing. please suggest how to implement keep alive in anci c library

http://www.gurux.fi/Gurux.DLMS.Client

int com_keepAlive(
connection *connection)
{
int ret;
message data;
gxReplyData reply;
mes_init(&data);
reply_init(&reply);
if ((ret = cl_keepAlive(&connection->settings, &data)) != 0 ||
(ret = com_readDataBlock(connection, &data, &reply)) != 0)
{
printf("Write failed %s\r\n", hlp_getErrorMessage(ret));
}
mes_clear(&data);
reply_clear(&reply);
return ret;
}

Thanks
Mohan Raj
