@heather just FYI. I have attempted to do this on my work computer with the same result.

Is there somewhere I should log MMW problems? We often struggle with the timeseries viewer – it takes a long time to load. Is this a common problem? I thought perhaps it might be caused by our location (New Zealand).

Just adding to this thread.  I have had this twice.  Tonight I couldn’t find a solution despite trying different browsers and incognito mode.

I agree, it is a bit of a show stopper.

Further update. My modular sensors code is logging to MMW flawlessly. I never thought I would see the day! Obviously something worked with Sara’s bypass code:

https://github.com/EnviroDIY/ModularSensors/blob/master/tools/LTExBee_FirstConnectionBypass/LTExBee_FirstConnectionBypass.ino

The only other thing I would like to know is how to code the settings into a standard modular sensors code so that my LTE doesn’t forget them.

Thanks again Sara!

James (& the rest of the UoW team)

And here’s the bypass output. I think this worked! Any idea why, and how I could transfer to my modular sensors code?

Sigh, so I thought we had this but I’m getting the same result.  My code is below, as well as the serial output.

Any thoughts?

Thanks so much for your help. I will try this tonight when I get home!

Have a wonderful Christmas.

Thanks for the prompt reply Sara.  You must love these LTE’s by now!

I have had some feedback from Spark who suggest that they have lots of other SARA R410M devices running on the network.

Sara, does the information below mean anything to you?  I figure that I would construct code using “gsmModem.sendAT(GF(“”)) ” to send these configurations to the LTE?

Just a further update on above.  The IoT provider thinks that the UBlox needs to be told to register.

He suggested using the AT commands:

AT+CPIN?
AT+CREG?
AT+COPS=?

Am I correct in assuming that the way to do this would be via the code below:

gsmModem.sendAT(GF("CPIN?")); gsmModem.waitResponse(180000L, GF("S"), GF("ERROR")); while (Serial1.available()) { Serial.println(Serial1.readStringUntil('\r')); } gsmModem.sendAT(GF("CREG?")); gsmModem.waitResponse(180000L, GF("S"), GF("ERROR")); while (Serial1.available()) { Serial.println(Serial1.readStringUntil('\r')); } gsmModem.sendAT(GF("COPS=?")); gsmModem.waitResponse(180000L, GF("S"), GF("ERROR")); while (Serial1.available()) { Serial.println(Serial1.readStringUntil('\r')); }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

gsmModem.sendAT(GF("CPIN?"));     gsmModem.waitResponse(180000L, GF("S"), GF("ERROR"));     while (Serial1.available()) {         Serial.println(Serial1.readStringUntil('\r'));     }       gsmModem.sendAT(GF("CREG?"));     gsmModem.waitResponse(180000L, GF("S"), GF("ERROR"));     while (Serial1.available()) {         Serial.println(Serial1.readStringUntil('\r'));     }       gsmModem.sendAT(GF("COPS=?"));     gsmModem.waitResponse(180000L, GF("S"), GF("ERROR"));     while (Serial1.available()) {         Serial.println(Serial1.readStringUntil('\r'));     }

Hi,

I have a similar issue with our Xbee3 LTE.  I have the hardware set up identical to how Letsid has it above. I am using the ‘LTExBee_FirstConnection.ino’ code, with the only amendment being a change of the apn to ‘m2m’ (as required for the Spark network).   The serial output I get from this code (after the initial setup) is: “Signal quality = 0”, over and over.  I left this for an hour and still got the same message.

I have a few questions/comments that might get me a step closer:

1) Do I need to do anything to the sim before inserting it?  Cellphone sims need to be activated, but the instructions from the NZ IOT provider (Spark) suggested that I should just insert it, turn on the LTE and then ‘test’ it from their developers portal.

2) Cell signal is unlikely to be the problem as I am testing this at my house in an urban area.  However, is there a way I can query the LTE to see what signals it can see (rather than connected signal) to determine if the antenna is the problem?

3) Spark provides 3G, 4G, 5G and CAT-M1 coverage (Spark NZ network coverage).  CAT-M1 seems to be the most appropriate for this method.  Should I be doing something different to specify that I want to use the CAT-M1 network as opposed to the 3G or 4G?

4) I understand network bands need to align with the capability of the Xbee3 LTE.  Spark CAT-M1 operates on Band 28 (700MHz) and Band 3 (1800MHz).  The LTE seems to support bands 1, 2, 3, 4, 5, 8, 12, 13, 17, 18, 19, 20, 25, 26, 28 and 39, therefore I don’t think this is the problem.

5) Is there anything else that anyone can think of that might prevent the LTE from working here in New Zealand?

6) Would I have more success with a Hologram sim?  These operate on the Vodafone network in NZ, but at least my methods would align with everyone else.

5) Another option would be to purchase a developers board and ensure that network connections are addressed in XCTU rather than operating blind on the Mayfly.  Would this help?

As always, thanks for your help.

Regards,

James
