MDBT42Q,2v04 run a scan every second and save wanted resault

why I don't see the name of the device "david-Iphone", "My-computer" ? like I see when I scan using my phone?

"My-computer"/etc is probably using Bluetooth, not bluetooth LE

getTime() but he gave me 821.90802001953

Turn on Set time on upload in the IDE comminications settings and upload some code. The default is 'on' so I'm surprised it's not ok.

(new Date()).toString() should then give you a nice date

is there any way I can save the data as text\json ? and then upload it to my device ?

I just answered this in one of your other posts

after I save the wanted devcies after scan , is there any way to know how much free space I got left on the devcie?

process.memory()
