Ok then I will go the hard way 🙂

The electronic lab of our university owns a spectrum analyzer. Next week I will try to investigate which command produces traffic and which not 🙂

Im a little bit overcorrect in building clean solutions. Sorry for consuming your time 🙂

@uta I might be biased, but I love it. Thanks a lot - great work 👍

@Cher Hi, looking at your screenshot, I think there is a bug in the modem firmware. If you look at the logs on the right you can see:

+CPIN: RE DY

This means the sim card is detected and ready. However, one letter is missing. This is supposed to be +CPIN READY. So I think the serial tool is therefore failing to interpet the correct string.

Can you query the CCID/IMSI? If it returns a number then the sim card is for sure working. You can also try updating the firmware

hey, I have a new device (kind of an IOT device) with eSim, it is supposed to be prepaid, but I don’t know how to check the details, and whether it has global data plan already.
I don’t have the number, can have the imsi number

the embedded sim is MFF2-QNF8

how can I proceed?

#eSim #germany

hey, I have a new device (kind of an IOT device) with eSim, it is supposed to be prepaid and activated, but It is not connecting and I don’t know how to check the details, and whether it has global data plan already.
I don’t have a phone number or anything, can have the imsi number.

the embedded sim is from the family MFF2-QNF8

how can I proceed?

Thanks

The problem is, I bought this from a private person used on ebay. I hope they answer next week on my mail.

@afzal_m Sounds good, how about BG600? - it has a similar FW to BG95/96

Hi all,

Please note that network time is now also provided over our LTE-M network in Germany, and can be retrieved with the usual AT commands (e.g. AT+CCLK?, AT+QLTS=2, …)

Thansk Roalnd. Sorry for the delay… had another project. This works for me as well and now I can continue.

@Roalnd-Baldin Has this been rolled out already? Do you have any idea when we can expect it? Thanks in advance!

@Roalnd-Baldin
Thanks for helping, but not working.

AT+CSOSEND=0,22,"48656c6c6f20576f726c64" OK

Sim7020 working with hex length, not with the byte, so I tried with hex format, but the message not arrived the iotcreator and Beecaptor.
Can you anything idea?

Thanks all!

Hi Eben,

Quick feedback: I can use GNSS and TCP at the same time using the SIM7000E using the latest firmware, which I had to update beforehand.

Best Regards,
Daniel

@Florian-Duecker I am using T-Mobile NB IoT sim card. I already sent you the ID of the sim card so you are suggesting me to order a new sim card from link you sent? I’ll check it.

Unfortunately it didn’t work out, what we tried yesterday. Please follow this topic for new updates.

@Roalnd-Baldin Cool! Nice to see it works now.

@Martijn-Kooijman I solved it by checking the return message after sending “AT+USOCR=17,7000”. Once it is contains “+USOCR: 0” in the returning string I know it is ok:
(it takes about 5 s after a reset)
added code:

String check_sara=cmd("AT+USOCR=17,7000"); while ((check_sara.indexOf("+USOCR: 0",1)<0)) { delay(500); check_sara=cmd("AT+USOCR=17,7000"); Serial.println(check_sara);//just for checking }

@Crowdsourcer I don’t know. BQ24195 is pretty solid. Probe it if you need to.

Hi Tibor,

Did you succeed to connect?
I want to use the Boron to.

Problem solved. It denpends on the sim card

@inge-eriksen
Hi Inge,

all of our SIMs for M2M and IoT are G-SIMs, which means that technically they are always roaming. So a query for the registration state, for instance with AT+CEREG, should always yield: 5.
On our testcards, we have currently no HPLMN deployed. For this reason the modem searches for a suitable network and will consider any NB-IoT network on the supported bands.
To make sure that the modem will only connect to the DT network, you can either fall back to manual network selection (PLMN-Id=26201), or restrict the supported bands to band 8. This will exclude any operators in Germany for which we have not yet roaming agreements.

Best regards,
Thorsten

Edit:
Just after posting, I struck upon this topic and was able to succesfully connect.
Now I’am figuring out how to setup the socket and start sending Hello world! messages.

I will do my best to keep you updated!

@hans-van-de-meent Ok top!
