App for Iphone
Here is the question:
In order to determine the RSSI before commissioning an application, it is important to know the data reception level of the IoT-network. Are there any test devices / apps for that?
Unfortunately, there is no app for the iPhone because the iPhone would have installed an NB-IoT-capable modem upfront. The iPhones do not have it. The easiest way to check the data reception level is to use an NB-IoT modem.
