Questions about nRF9160dk

[KyeongTaek Jeong]

Hello~ I have previously written related articles. But I don't get the answer I want, so I ask you again.
Use the toolchain manager to use ncs 1.3.1. The error as shown in the process of setting up the SES is generated.

There are many difficulties because it is my first time using this board. Thank you for your help.

1. What should I do with this problem?

2. The nRF9160_pca10090 is not visible in the Toolchain manager.  Instead, nRF9160dk_nRF9160 appears. Is it the same thing?

3. You are trying to communicate wirelessly with two nRF9160dk. Do I have to use SES? Or is there another way?

4. Is the GPS that appears on the nRF Cloud and LTE Link Monitor the same principle?
While GPS appears in the LTE Link Monitor, data is not received in the nRF Cloud. What's the reason?

Please allow time for us to answer, we are not working 24 hours.

 Regarding this issue, please see your previous ticket #257463

 I don't understand. Can you please elaborate?

 No, nRF Cloud and LTE Link Monitor is not the same. GPS in LTE Link Monitor is the position of the LTE tower you are connected to, not the nRF9160 itself.

If you are not seeing GPS data in nRF Cloud, what application are you running on your device? I suggest programming the Asset Tracker to test the GPS functionality.

Kind regards,
Øyvind

Let me repeat the third question.
I'm going to use two "nRF9160dk"s to communicate wirelessly(LTE-M)
How can I do it? Do you have a simple example?

[Øyvind]

Please see Simple MQTT sample which can be used to communicate between device. No direct communication possible. 

Kind regards,
Øyvind

[KyeongTaek Jeong]

hello, What you said is that LTE-M does not work like the image below?

[Øyvind]

Hi, 
Yes, that is correct. I have forwarded the question as well to verify, and to see if there is another solution. 

Will get back to you within the day.

Kind regards,
Øyvind 

[KyeongTaek Jeong]

Thank you. If there's any other way, please let me know. I'd appreciate it.

[Øyvind]

Sorry for the delayed answer. 

No, D2D is not possible as it will go via network infrastructure, and is not part of the eMTC (enhanced Machine Type Communication).

Kind regards,
Øyvind

[KyeongTaek Jeong]

Thank you. I found out that D2D is impossible.
Then, can i communicate like a alkie-talkie? Is that MQTT?

 I don't understand. walkie-talkie is the same as D2D is it not?

MQTT is a messaging protocol: https://mqtt.org/
