Reach (base) own AP can't turn on

Yesterday I measure some land parcel. My base and rover were connected to my smartphone. After finished setup base, I try to turned on base AP. Then my smartphone connection to the base was lost. I was trying turned on my smartphone wifi to searched base AP, but I couldn’t find it.
Then I try to my rover, I got reach rover AP.
Maybe someone in this forum can help me.
Thank you

Reach operates either as a client or as an AP. When you turned on AP on your base it is reasonable that Reach disconnected from your phone network.

I connected to reach (base) in my smartphone wifi connection, then when I finished setup for base, I turn on the reach wifi, so I couldn’t access with my smartphone wifi, I try ti turn on my wifi to access base AP, but I couldn’t find it.
