Lastest version: 1.71 released 1 September 2020

  • Version 1.71 fixes an OTAA re-join bug:
    After sending 32768 packets, the LoRa Remote Power Switch issues an OTAA Join request and resets the packet counters when the OTAA join reply is received. However, when the LoRAWAN packet logging function is switched OFF the received NwkSKey and the AppSKey are not correctly saved to the EEPROM of the LoRa Remote Power Switch. This causes the LoRa Remote Power Switch to lose connection to the LoRaWAN server.
  • Workaround for software versions 1.60 and 1.70:
    Switching  the LoRaWAN packet logging to ON will prevent this from happening in software versions 1.60 and 1.70.


Download the manual and turn to chapter 7 to see how to perform a software update.
