A strange ranging test with 1280

Semtech Transceivers

Hello,

I am doing the ranging test of 1280 and I find a strange phenomenon. I use a Master and a Slave to do the experiments. But when I shut down the Slave, only left Master powered on, I can still get ranging results occasionally，maybe once for several seconds. How could this happen?

Thank you
Best regards

Hi Sun.

What do you mean by “still get ranging results”. Do you mean from the slave? Being shut down?
If you get those results from the master, I need more details about what do they exchange, so that the master can estimate the range.

Regards,

I dont know where the ranging results are from. In fact in my experiment, only one 1280 master node is working. When I powered on the Master and the Slave, I can get the ranging results, but when I shut down the Slave, the output from the Master stopped for several seconds and then output a result.

Regards,
