So I did a highly scientific field test to see if moving cable and unit around would reveal anything. Results were puzzling.
The first time I powered up, the home page showed Voltage warning and Throttle from the get-go. I moved cable around, shook unit, sat it in the sun etc. Nothing changed.
So I unplugged the battery, left it for a minute, then powered up again. This time, voltage fine, no throttling, everything OK. I shook it around, sat it in the sun, flexed the cable all over the place. Nothing changed, no throttling, no voltage warning.
I left it running for about 90mins, gave it another few shakes during that time and still no change.
I inspected the log afterwards, I don't know how to read it, but the only thing which maybe looked odd was a bunch of these which started showing up in high volume after about an hour.
$PALOG,20200529,113658,DEBUG,MODEC-FILTER-PASS,4073FD,223,SIG,200,MAX,170,FILTER,1730,VDIFF
$PALOG,20200529,113659,DEBUG,MODEC-FILTER-PASS,4073FD,223,SIG,200,MAX,170,FILTER,1730,VDIFF
$PALOG,20200529,113659,DEBUG,MODEC-FILTER-PASS,4073FD,223,SIG,200,MAX,170,FILTER,1729,VDIFF
$PALOG,20200529,113659,DEBUG,MODEC-FILTER-PASS,4073FD,223,SIG,200,MAX,170,FILTER,1729,VDIFF
$PALOG,20200529,113659,DEBUG,MODEC-FILTER-PASS,4073FD,223,SIG,200,MAX,170,FILTER,1729,VDIFF
And a number of these randomly interspersed about 5 mins apart:
$PALOG,20200529,105334,PAWRT,400BC1,TIMEOUT
So I'm not sure what to conclude from that - perhaps a poor/dirty USB connector (cable to battery), or maybe I got unlucky with the battery and it's a faulty one. I can try a different battery. Changing the cable is more of a hassle.
The other thing I have observed is that when running SD on the iPad, if you put SD to background (e.g. to check another app), and ipad goes to sleep mode, then you return to SD, the dreaded "Waiting for Device" appears, and it doesn't automatically reconnect. Is that expected behaviour?
Thanks again.
