Now that Keiron Smith has corrected me in that I Do have the latest firmware 1.3.4, I nevertheless have a connection problem.
"SkySafari Pro can make a wireless connection to the scope, but the scope is not responding. Make sure the scope is powered on and connected correctly. Also make sure you selected the correct scope type."
New SkyFi 3 with firmware 1.3.4
SkySafari Pro 22.214.171.124 running on a Pixel 6
Celestron Evolution with Starsense firmware firmware ver 01.21.2133 the latest.
Using connection preset for Celestron NexStar GPS/SLT/SE, Access Point (Network access didn't work either)
The unavoidable, cannot turn off, Celestron Wifi radio is on channel 6.
The SkyFi 3 radio is on channel 10. Both are 20 dB or so above neighborhood signals. I'm testing at the scope.
I performed a Solar System align on the Sun, inside the house.
The mount was aligned and tracking because a GOTO using the controller to Mercury moved the scope the likely amount.
Oh, the USBA to Mini-USB cable has been successfully used to perform Celestron firmware updates. Don't know where it came from.
The Preset setup test connects to SkyFi successfully.
Today I even connected the scope to Stellarium running on a Linux desktop. The software showed the Evolution on the Sun. I could Goto Mercury, Denebola.
Some screen shots are at the following Google Drive folder - safe.
Thanks for any help. I have another cable arriving tomorrow.
