AS923 dwell time limitation for Australia

[arjanvanb (Arjan)]

Apparently the network may explicitly enable it, or needs to explicitly disable it? The LoRaWAN Regional Parameters 1.0.3 says for AU915:

The default JoinReq Data Rate is DR2 (SF10/125KHz), this setting ensures that end-devices are compatible with the 400ms dwell time limitation until the actual dwell time limit is notified to the end-device by the network server via the MAC command TxParamSetupReq.

AU915-928 end-devices MUST consider UplinkDwellTime = 1 during boot stage until reception of the TxParamSetupReq command.

The TTN Community network is using LoRaWAN 1.0.2, for which the Regional Parameters 1.0.2 Rev B don’t seem to mention this. Also, it’s not clear if TTN does send TxParamSetupReq for AU915. And it seems nothing similar is defined for AS923 in 1.0.3 either. Finally, I don’t know what TTN and your device’s LoRaWAN stack do for AS923.

@arjanvanb

a maximum dwell time is a regulation of one’s country, not something TTN has introduced. So, no, TTI cannot waive that.

I think this still applies. But regardless: it seems TTN/TTI would also need to send the proper LoRaWAN MAC commands to configure the device if the maximum dwell time does not apply to one’s region.
