Since Subsurface 5.0.8 was crashing sometimes during repeated tests,
I went back to 4.9.7 which seemed to be crash proof in the exact
same radio environment.
Distance from my Mac to the i770R: 30 cm.
i770R RSSI: -62 dB
Nb of other env. BT equipments: 9
best RSSI: -54 dB
Here are my results on 30 attempts to just download from the i770R
and then exit without saving:
----------------
success failure
----------------
22 8
----------------
Strange behaviour: the time to get an answer either success or failure
seems to vary from 2 s to 30 s. Is this coming from the underlying
BT driver?
Here are included 2 subsurface log I got with the -vv arg.
Based on the information in the failure log file:
qt_ble_open( {c7d52420-5e99-4800-a1bc-e5b07b2d0770} )
trying to connect
timeout while trying to connect to the controller
{c7d52420-5e99-4800-a1bc-e5b07b2d0770}
Finishing download thread: "Unable to open LE:{c7d52420-5e99-4800-a1bc-e5b07b2d0770}
Aqualung (i770R)"
This is a problem at the bluetooth (or driver) layer. Subsurface is unable to
connect, so we don't even get a chance to communicate with the dive computer.
