Hi Stefan,

you are a cool guy!! This solved the problem. It was the whitespace.

Many many thanks for your support!!

Regards, Roland

Hi Stefan,

again many thanks. It works now. I can send data to my App. The following sequence works for Quectel BC66:

Deactivate auto sleep mode

AT+QSCLK=0

Persistent network and APN setup

AT+QBAND=1,8
AT+CFUN=0
AT*MCGDEFCONT="IP","cdp.iot.t-mobile.nl"

Restart the module as some configurations only take place after a reboot.

AT+QRST=1

After reboot wakup from sleep, deactivate auto sleep mode again and wait for network connect

AT+QSCLK=0

+IP: 10.128.0.134

Create a UDP socket and for UDP server

AT+QIOPEN=1,1,"UDP","172.27.131.100",15683,1001,0,0

Send message “Hello World”

AT+QISEND=1,11,48656c6c6f20576f726c64

Hi Mario,

Tuino 096 is an Arduino Zero (M0) compatible board. Grove Base Shield V2.0 doesn’t support this explicitity.

I recommand to try"ARDUINO MKR CONNECTOR CARRIER (GROVE COMPATIBLE)" instead. With this shield you can bridge from Zero/M0 to sensors with Grove connectors.

Hi Joop,

I will fix this.

Could you please give me your IMEI?

Hi Petr,

if I understood you right I see the following challenges:

1. find a location with NB IoT coverage.
2. attach your device to the NB-IoT network of T-Mobile Czech.
3. send messages via UDP to Cloud of Things
4. decode the payload of your UDP message and integrate it with Cloud of Things

Please let us get directly in contact, that we can speak about it (roland.baldin@t-systems.com).

Regards, Roland

@Stefan-de-Lange Hi Stefan, nezwork specialists developed a simulation tool for NB-IoT devices with which it is possible to understand the power consumption and battery live time by simulating different protocolls and NB-IoT features.

Let me try ro access to it. We can have a conf-call and play a little bit with it. Maybe it is interesting for us.
I guess my colleagues are interested in our feedback about it.

Regards, Roland

Hi,

I did “normal” TCP/IP MQTT on top of NB-IoT connection with the Quectel BC66. So TCP/IP is possible. But I didn’t try to post a normal HTTP request.

LWM2M is implemented on top of CoAP and UDP. By this it works perfectly on NB-IoT. It is also supported by Quectel BC66. We tested it successfully with Eclipse Leshan server and the Nokia Impact LWM2M server.

@Ronan-Lacroix I have a question: The min value for T3412 is only valid for the “extended” version of TAU ? Does the 1 hour apply also to the min. value of standard TAU or is it shorter?
Having a min TAU of 1 hour seems to me for many use cases difficult because the devices in those use cases need to wakeup from sleeping much more often (e.g. every 10 minutes).

Many many thanks for your support!

@Eben-van-Ellewee @Stefan-de-Lange Many many thanks for this hints! I will take this to our doc and dev team.

Regards, Roland

@Eben-van-Ellewee I opened the page with Chrome, Internet Explorer, Firefox. Additionally I did a “Save as” with Chrome and I also did a “GET” of the URL with Postman. In any of those cases I didn’t get any security complains of my HTTP client or the proxy.

Two days ago we had an outage for some hours of our documentation library. Maybe your problem has been caused by this.

Regards, Roland

@Marijn many thanks for this . I am highly interested in this.

@Mert-Karabagli Hi,

IoT Creators is the bridge between the device/connectivity world and the application world. You can configure IoT Creators to forward the UDP payload of your device to any HTTP endpoint of your application (web-hook).

Beeceptor is only an example for an HTTP application endpoint to explain how the data is forwared from IoT Creators. It doesn’t provide any application logic to store or to visualize your data.

If you want store and visualize the data without develop your own application you need to integrate forward the data to an generic IoT platform such as Axonize, All Thinks Talk, Thingsboard, Cloud of Things, etc.

We are currently documenting how those integrations look like. Unfortunatelly we don’t have it available now.

Regards, Roland

The CoAP stack of the CoAP server is based on Californium version 1 and uses the implemenation as it has been pushed by OceanConnect from Huawei. Although this implementation is not 100% standard compliant there are ublox n211 and quectel bc95 in the market which support this floavor of CoAP

I checked the AT command guide of the SIM7070G. It looks like only the standard CoAP is supported.

IoT Creators will provide the standard complient CoAP stack in Q1 2021.

Hope this helps.

Regards, Roland

Hi Marijn, this is a very interesting question

I guess it is not that high as one would hope because the antennas of the radio stations are optimized for the horizontal propagation of the radio signals, not so much for the vertical.

@Cees-Meijer I just got an error message that the email couldn’t be delivered to you email address. Could you please send an email to support@iotcreators.com to make sure I am using the right address?

Thanks!

Cheers.

@Cees-Meijer I deleted you last post because it contained your IMEI. You created a a support ticket for it and work on it.
