MKR NB1500 doesn't work with AWS MQTT #23

Closed ravelab closed 5 years ago

ravelab commented 5 years ago

Hi,

I'm using ArduinoBearSSL. I am able to get MKR1000 to work with AWS MQTT server, and MKR NB 1500 to work with Google MQTT server. However, I am unable to get MR NB 1500 to work with AWS MQTT server using the "AWS IoT NB" example. It is stuck at AT+USOCO=0,"XXX.iot.us-east-2.amazonaws.com",8883 and timeout after 5 minutes:

Attempting to connect to MQTT broker: XXX.iot.us-east-2.amazonaws.com
AT+USOCR=6
+USOCR: 0

OK
AT+USOCO=0,"XXX.iot.us-east-2.amazonaws.com",8883
ERROR

+UUSOCL: 0
AT+USOCL=0
ERROR
0000-00-00T00:00:00Z MQTT connect error: -2

Any ideas? Thanks

Hi @ravelab,

XXX.iot.us-east-2.amazonaws.com does not appear to be a valid host name to me:

$ ping XXX.iot.us-east-2.amazonaws.com
ping: cannot resolve XXX.iot.us-east-2.amazonaws.com: Unknown host

To connect to AWS I would suggestion the following: 1) Follow the first part of https://docs.arduino.cc/tutorials/mkr-wifi-1010/securely-connecting-an-arduino-mkr-wifi-1010-to-aws-iot-core to setup the private key and public certificate 2) Run the following sketch, instead of the WiFi one mentioned in the link above: https://github.com/arduino/ArduinoCloudProviderExamples/tree/master/examples/AWS%20IoT/AWS_IoT_NB

Hi @sandeepmistry yeah XXX is not an actual address. I followed those instructions, I can connect to aws via wifi, but not nb. I could connect to azure or gcp via nb though. We think it might be a carrier issue. Thanks

Hi @ravelab I'm also facing a similar issue, did you figure out if it really was a carrier issue or something else? thanks

ravelab commented 4 years ago

@zvikarp for me it was a ublox modem firmware issue

Hi @ravelab I am also facing the exact same problem, could You please describe maybe a little bit how You fix the modem firmware issue? Did You update the Firmware of the U Blox Module? And how did You update? Thanks for Your help.

@Ar00001 Below is a link that show how to update the modem. You have to contact u-blox to request the later firmware.

the links do not work anymore. Any idea how to get to the projects?
