The hotspot is able to get the OTAA Join Request from End Device on EU region. but due to block chain is CN region, Server will send the Join -Accept in CN region, so end device can't get the OTAA Join Accept. 649 + 650 + 651 +For example, if you are in USA, you have to use the US915 frequency plan.
