At the moment, there are a few different versions of the LoRaWAN® specification that are available to developers. Each supports slightly different functionality. So, which version should you use when developing LoRaWAN-based solutions?
The short answer is that the most current version of the specification for which there is a Certification program is LW 1.0.2. The Certification program for LW1.0 has been withdrawn and the Certification Program from LW1.0.1 will be withdrawn at the end of 2019.
While LW 1.0.2 is the most stable, you may want to consider using LW 1.0.3. This version of the specification adds support for Class B functionality; however, in the United States, there is a minor change that has delayed creation of a Certification test. For more information about certification, take a look at the Certification page on the LoRa Alliance website.
