[Embedded World 2020, Nuremberg] Alternative eSIM setup for non-supported countries by iBasis

[redshifter]

Hi Support,

I need to use another eSIM not the iBasis, because the company those not have roaming coverage in Bulgaria.

Question: If I use a IoT eSIM card Telefonica Germany, what eSIM cards details need - SIM ICCID and PUK code? Is this enough for a new SIM registration on NRF Cloud service?

[Jon Helge]

If you have other sims than the bundeled iBasis you do not need to activate the sim at nRFcloud.

I need first to an active eSIM to the feeds of data from the sensors into the nrf cloud through the nrf APIs.
What are the other options to get the sensors data?

Q: Should I purchase another Nordic dev. board for prototyping and if so, what is the list of devices and cables for a full starting kit for LTE-M for example?

The nRF9160 DK has a on-board debugger, and is recommended if you want to do development and prototyping. If you want to use the on-board debugger on the nRF9160-DK to debug the Thingy:91, you'll need a 10-pin cable to connect from the "DEBUG OUT" port of the nRF9160-DK to the thingy:91, similar to this:

Hi Sigurd, only the secondary question about the developer board setup was answered.
I still don't understand how to track the sensor data (temp, humidity & VoS - gas) & GPS location without an eSIM card. I can I see the sensor data & GPS location by the debugger?

Sigurd about the external debugger options, will Segger's J-link EDU mini will be enough?

> you don't need to add the SIM to nRF Connect for Cloud

just means, that "nRF Connect for Cloud" doesn't require your SIM being registered to receive data. But, for sure, your device (nRF9160) requires a SIM to connect to your mobile provider and so send data to "nRF Connect for Cloud". But you can use any SIM from your mobile provider supports and you don't need to register that SIM at "nRF Connect for Cloud".

> about the external debugger options, will Segger's J-link EDU mini will be enough?

AFAIK, that "mini" has no "voltage-level-shifter", so I guess, it can not be used, though the nRF9160 requires 1.8V and not the supported 3.3V.

(And the EDU*s are for no commercial use only :-) ).
