Hi ox-banish. The ping slot frequency and data rate you specify in the device profile is sent to the device in the PingSlotChannelReq
MAC command. This MAC command is sent by the LNS in a class A receive window, and before any ping slot downlinks should occur. And if this MAC command specifies a frequency of 0, the device should use the default frequency plan (hopping). So then, some questions:
- what is your device?
- what LoRaWAN spec version does it implement?
- does your device receive the
PingSlotChannelReq
MAC command? - does it contain the values you specified in the device profile?
