not getting history data off device #5

Closed Commander1024 closed 5 months ago

Commander1024 commented 4 years ago

Ohai,

I bought myself a GMC 320 Plus (GMC-320Re 4.53). Most of this tools function work on this device and give reasonable output like -i, -o, -O, -G, -T and --heartbeat etc.

But it seems like it cannot get the history:

python2 ./gq-gmc-control.py -p /dev/ttyUSB0 -d device found: GMC-320Re 4.53 storing data to '/tmp/tmpTFmCQ4.bin' address: 0x000000, size: 4096, total size: 1 bytes (0%) address: 0x001000, size: 4096, total size: 2 bytes (0%) address: 0x002000, size: 4096, total size: 3 bytes (0%) address: 0x003000, size: 4096, total size: 4 bytes (0%)

This run won't finish (within a reasonable time).

resulting .bin file looks pretty empty:

hexdump gq-gmc-log.bin
0000000 0055 0000 ff00 ffff ffff ffff ffff ffff 0000010 ffff ffff ffff ffff ffff ffff ffff ffff 0000080 ff55 ffff ffff ffff ffff ffff ffff ffff 0000090 ffff ffff ffff ffff ffff ffff ffff ffff 00001f0 ffff ffff 00ff
00001f5

Is there any additional info I can provide for debugging?

Unfortunately from revision GMC-500+Re 2.x on they changed to protocol, the library was designed using the Re 1.x firmware. See issue #3 for more info.

I have the exact same problem as the OP. I also tried https://github.com/ThomasHabets/gq-gmc-control but it doesn't change anything. GMC-300E. Help please, I need to get the data off this device to the linux workstation ASAP! What is the company doing?
