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.
The GSMA offers a “Mobile IoT Deployment Map”. You can click on a country and see various information per technology type e.g. which operator deployed that network type and even URL’s of the operators’ maps for that country (if the MNO made it available). GSMA is improving and enhancing it continuously.
every module supplier implement their own Maximal Transfer Unit (MTU). They can reach up to 1.358 Bytes.
If the message is larger than the MTU, the message should be divided into smaller messages.
We only limit the amount of data per month and the number of daily messages per device.
