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
