MQTT ERROR rejected, only shared feeds may be published to Moderators: adafruit_support_bill, adafruit

[jimk123]

try to follow the geofence guide here:
https://learn.adafruit.com/geofencing-w ... dafruit-io

in my code it defines the feed as:
const char LOCATION_FEED[] PROGMEM = AIO_USERNAME "/feeds/location/csv";
Adafruit_MQTT_Publish location_feed = Adafruit_MQTT_Publish(&mqtt, LOCATION_FEED)

it did not say anywhere in the guide to manually create the feed but I ended up creating one called 'location' after getting errors

in the serial window it says it successfully published the lat and lon values:
Publishing location: 0,41.898823,-72.676041,28.300001
Publish succeeded!

but when I look at https://io.adafruit.com under profile i see this error message pop up every 30 seconds ( I have a 30 second delay in the code):
MQTT ERROR: xxxxxxxxxxxxxxxxxx 172.58.238.198 PUBLISH ,,11,8,,,44,, OK -72.676067,29.200,0.17,269.1,1,,� rejected, only shared feeds may be published to

I have been using adafruit IO for a few weeks with some other boards publishing temp, humidity, etc but the feed name is always one value like 'temp' the one in the geofence code is called feeds/location/csv, not sure if I need to define something else in IO ?

I'm having the same problem when running Adafruit's Treat Tracker project, but the mqtt_fona example works fine. Haven't yet figured out how they publish differently, but some tips from Adafruit would be welcome.

The "only shared feeds may be published to" error message means IO didn't recognize the MQTT topic as being in the standard "{username}/{type}/{key}/{format}" pattern with "feeds" or "f" in the {type} slot and it didn't find the username you authenticated with in the {username} slot. For example, if I (abachman on IO) have a feed with the key "temperature", the topic I publish to would be "abachman/feeds/temperature/csv".

In the case of this example:

Code: Select all | TOGGLE FULL SIZE

const char LOCATION_FEED[] PROGMEM = AIO_USERNAME "/feeds/location/csv";

It may mean AIO_USERNAME is unset. It could also mean there's another publish event in the sketch that's using a different topic. Hard to tell without seeing source code.

Are you able to paste your sketch inside \[code\] tags with your IO key taken out?

Rereading the original error message, "PUBLISH ,,11,8,,,44,, OK -72.676067,29.200,0.17,269.1,1,,� rejected ..." means IO received ",,11,8,,,44,, OK -72.676067,29.200,0.17,269.1,1,,�" as the MQTT topic, which is not a valid MQTT topic.

For the treat tracker, I changed

Code: Select all | TOGGLE FULL SIZE

const char PATH_FEED[] PROGMEM = AIO_USERNAME "/feeds/" PATH_FEED_NAME "/csv";
Adafruit_MQTT_Publish path = Adafruit_MQTT_Publish(&mqtt, PATH_FEED);
const char GOOD_CANDY_FEED[] PROGMEM = AIO_USERNAME "/feeds/" GOOD_CANDY_FEED_NAME "/csv";
Adafruit_MQTT_Publish goodCandy = Adafruit_MQTT_Publish(&mqtt, GOOD_CANDY_FEED);

to

Code: Select all | TOGGLE FULL SIZE

Adafruit_MQTT_Publish path = Adafruit_MQTT_Publish(&mqtt, AIO_USERNAME "/feeds/treat-path/csv");
Adafruit_MQTT_Publish goodCandy = Adafruit_MQTT_Publish(&mqtt, AIO_USERNAME "/feeds/treat-good-candy/csv");


Essentially hardcoded the URL, which fixed my error.

Maybe you can adapt this to the geofence example.

jefish,

Thanks for the update. I've patched the treat-tracker code.

[jefish]

Groovy.

Can you confirm that this change will also make the geofencing example work better for jimk123?

It should - I don't currently have hardware to test it out.
