Topic 1: Installation

Question: For my project I need to connect to a P2M module located in a quite unpopulated area. How can I figure out, if a specific target geo position is covered by a mobile network?
Answer: As a starting point, the GSM Association (GSMA - Global System for Mobile Communications) provides network coverage maps for each country in the world, broken down by technology (GSM, LTE, etc.) and network operator: https://www.gsma.com/coverage/ On top of this, some tools can provide further information about nearby network access points (cell towers), For example, iPhones users can try this app: https://apps.apple.com/de/app/cellular-tower-signal-finder/id6470660460

Topic 2: Module Hard- and Software
___________________________________________________________
Question: Can I add or modify the embedded software of a P2M* module somehow?
Answer: No, typically not. P2M* modules are OEM standard products which are offered as a "black box" with a fixed set of functions and an API for integration purposes. But customer-specific hard- and software modifications are available on request. Please contact:

Question: Can I use the 4 digital inputs to monitor a digitized parameter, e.g. the ambient temperature originated from a sensor?
Answer: P2M*DIO8 digital inputs are 1-bit ports which have been designed to read binary information originated from a switch or button or similar electromechanical component indicating a certain event or situation, e.g. an open door. The P2M device will return the actual status of each input port by SMS - separately. But, as four 1-bit input ports are available, these four input bits potentially can represent a coded digital value with an overall resolution of (up to) 16 bit. So, as a workaround, a user can read a multi-bit digital value, but has to do that sequentially, i.e. using separate SMS queries for each 1-bit input port.
