No eSIM, but we do have the following available:

MFF2 sim-on-chip nuSIM (the sim profile integrated in the cellular module)

Good morning @afzal_m, is it possible this Sim requires 3v? This would explain weird behavior when the module provides only 1.8v

Hi,

today we took a nice comort sensor (CO2/Temp/Humidity/BodySense) in Barcelona into operation.

We configured

21401 as PLMN ID for Vodafone Spain and used 20 for the frequencyband (800Mhz). cdp.iot.t-mobile.nl as APN for IoT Creators

It worked immediately without any problems.

@Roalnd-Baldin

The 2 hours is probably related to the 3GPP TAU timer, if it expires the device is implicitly released from the network I believe. Which is bad if you have a device that wants to sleep for more than 2 hours. So usually you set this value to whatever is the greatest the network accepts. You can run AT+CEREG=5, AT+CEREG? and check the returned values. It will tell you the timers that are used.

@Wessam Hi, have a look to https://forum.iotcreators.com/topic/626/how-long-does-it-take-that-the-network-detects-a-dead-ip-connection. Maybe it contains some info you are interested in.

@Malte-Neumann Hi Malte, please send the 10 ICCIDs to support@iotcreators.com . I will check them .

Please use as PLMN IDs from page https://docs.iotcreators.com/docs/telekom-iot-networks-in-europe

Regards, Roland

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

For the final reply, the datas that are being sent to beeceptor are forwarded to the HTTP endpoint in Turkey. I entered the url of the server In Turkey to the proxy settings on my beeceptor page. So now the problem is handled. Thank you everyone.

Kind regards,
Mert

@Holger-Wech you can use LTE-M instead of the 2G/3G fallback that is described in our quick start guide. Please use the APN internet.m2mportal.de for LTE-M.

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.

@Timo-Siekmann said in Limited Data Rate after to many messages on aday?:

Quectel BG96

Hi, please try:

AT+QCSCON=1
AT+CEREG=4

I highly suggest to plot the current too.

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

@afzal_m Proprietary sucks 😞 I hope more open protocols are added, UDP is pretty limiting

Hi Karl,
our network department is investigating this issue. We’ll get back at you asap.

@Stefan-de-Lange Sorry for the late response. I just tested it with udp via the IoT Creators platform.
Regards, Roland

Hi Petr,

if I understood you right I see the following challenges:

find a location with NB IoT coverage. attach your device to the NB-IoT network of T-Mobile Czech. send messages via UDP to Cloud of Things 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

Hi Adam,

the APN is always: cdp.iot.t-mobile.nl - independent of your location.

However, it is important to set the PLMN ID correctly according to your country. For Poland this is: 26002

All configuration details can be found here: https://docs.iotcreators.com/docs/general-settings

I hope that helped! Let us know whether this worked out or not!

@Stefan-de-Lange thanks for your feedback. We are deploying a more robust architecture in a few weeks’ time. That has confirmed performance improvements. Some pages you may try to load are top-heavy, so they can take a few seconds to pull down all supplier logos and product pictures (e.g. the modems page, where we have almost 150 modules integrated).

@Uta is referring to the IoT Solution Optimizer which can be found under the “SERVICES” node. If you click on the link under “virtual twin technology” in the description, you can open a product brief to learn more…

And speaking of learning more, under “LEARN” we have a lot of great information in the “Technology Cards” library.

Take care!
Miguel

@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.

May I suggest you also take a look at our central FAQ page for NB-IoT Roaming? 😉
