Information: mongoDB

[sebastien...@gmail.com]

Hello,

I have a question about data save in mongo database.

My configuration is:

- Rapsberry pi 3 b+ with Ubuntu server 18.04 for arm

- IC880a

- MongoDB shell version v3.6.3

- MongoDB server version: 3.6.3

I used "Handler" and  "Connectors" to record data in this database. Informations saved are "deveui", "data", "datetime".

I have this type of record in the mongo database:

[

       {

                "data" : "60AE610D4612B2AE0000",

                "deveui" : "000175C54167656E",

                "type" : "Up",

                "formatDate" : "2019-04-17 07:57:59"

        },

        {

                "data" : "00AD3B0E2E12ADC3C30E",

                "type" : "Up",

                "formatDate" : "2019-04-17 08:03:08"

        }

]

Sometimes, I have a record in database without "deveui" information. Why?

It's problematic for me, because I am doing lot of statistics on these datas. So If I have incomplete data, I can't worked correctly.

Thank you in advance for your answers.

Regards,

Sébastien Carobbio

Hello.

I suspect you have an ABP (non OTAA) device that has no DevEUI. Add the DevAddr to the list of fields. This will uniquely identify the device that sent the frame.

OK. Thank you for your help.

All my devices are activated by OTAA.

If the devaddr are correctly recorded in database, I could used it to identify devices.

I test this solution during a day and I do a feedback.

Have a nice day.
