Hi !
I'm doing some testing on mqtt with the nrf9160 DevKit.
So far, everything is working with TCP and TLS and I would like to use WSS. I started with WS but I can't make it work ...
Here's what I tried
In prj.conf, I added (seen on zpehyr's websocket documentation):
- CONFIG_WEBSOCKET_CLIENT=y
- CONFIG_MQTT_LIB_WEBSOCKET=y
and I modified :
-
CONFIG_MQTT_BROKER_PORT=80 (as mentionned on mqtt.eclipseprojects.io)
- CONFIG_NET_NATIVE=y
In the main.c I made some modification
client_init :
[...]
#elif defined(CONFIG_MQTT_LIB_WEBSOCKET)
client->transport.type = MQTT_TRANSPORT_NON_SECURE_WEBSOCKET;
struct websocket_request *ws_cfg = &(client->transport).websocket.config;
ws_cfg->host = CONFIG_MQTT_BROKER_HOSTNAME;
ws_cfg->tmp_buf = tmp_buffer;
ws_cfg->tmp_buf_len = sizeof(tmp_buffer);
client->transport.websocket.timeout = 2000;
#else
client->transport.type = MQTT_TRANSPORT_NON_SECURE;
#endif
return err;
}
fds_init :
static int fds_init(struct mqtt_client *c)
{
if (c->transport.type == MQTT_TRANSPORT_NON_SECURE) {
fds.fd = c->transport.tcp.sock;
} else {
#if defined(CONFIG_MQTT_LIB_TLS)
fds.fd = c->transport.tls.sock;
#elif defined(CONFIG_MQTT_LIB_WEBSOCKET)
fds.fd = c->transport.websocket.sock;
#else
return -ENOTSUP;
#endif
}
fds.events = POLLIN;
return 0;
}
In the debug terminal here's what I get
<dbg> net_mqtt_sock_tcp.mqtt_client_tcp_connect: (0x200153a8): Created socket 1 <dbg> net_mqtt_sock_tcp.mqtt_client_tcp_connect: (0x200153a8): Connect completed <dbg> net_mqtt_websocket.mqtt_client_websocket_connect: (0x200153a8): Connect completed --- 9999 messages dropped --- <dbg> net_mqtt_rx.mqtt_read_message_chunk: (0x200153a8): [CID 0x20015558]: Transport read error: -11 <dbg> net_mqtt.mqtt_input: (0x200153a8): state:0x00000006 .... <dbg> net_mqtt_rx.mqtt_read_message_chunk: (0x200153a8): [CID 0x20015558]: Connection closed. <dbg> net_mqtt_websocket.mqtt_client_websocket_disconnect: (0x200153a8): Closing socket 2 <inf> mqtt_simple: MQTT client disconnected: -57 <err> mqtt_simple: mqtt_input: -57 <inf> mqtt_simple: Disconnecting MQTT client... <err> mqtt_simple: Could not disconnect MQTT client: -57 <inf> mqtt_simple: Reconnecting in 60 seconds... <dbg> net_mqtt_sock_tcp.mqtt_client_tcp_connect: (0x200153a8): Created socket 1 <dbg> net_mqtt_sock_tcp.mqtt_client_tcp_connect: (0x200153a8): Connect completed <dbg> net_mqtt_websocket.mqtt_client_websocket_connect: (0x200153a8): Websocket connect failed (-53) <err> mqtt_simple: mqtt_connect -53 <inf> mqtt_simple: Reconnecting in 60 seconds...
What am I doing wrong here ? Some helps would be much appreciated !
Best regards,
