VBL2350 Not reporting Motor Speed for channel 2 was created by jetonski
Hi, I successfully updated the VBL2350 to the latest firmware 8-14-11, which was posted recently here:
dev.roboteq.com/dev1/online-forum/troubl...de-troubles#29525943
Unfortunately the device is still reporting 0 as the speed for motor channel 2 at all times. Motor speed control (open loop) works fine. It\'s just the serial ?BSR command that appears to have a bug.
In all other respects, the controller is working perfectly so far. I\'m driving two high torque brushless motors with frequent direction reversal at near max currents. It\'s nice and smooth at low speeds and direction transitions are seamless.
If this is more than a quick fix and an estimate of time to address is possible, it would be a big help. Thank you.

This is a bug that should have been fixed in the latest firmware. We\'ll check again. Pls stand by

Hoping to find a quick workaround, I tried installing the following microbasic script to query motor speed and post it to an unused configuration parameter:
Next I sent a Serial ~AMAX query. Speed for motor 1 was reported on channel 1, but channel 2 stayed 0. So Microbasic queries for motor speed channel 2 are unsuccessful as well.
Hoping this helps to track down the bug.
setup: \'one time init stuff
mainloop: \'our loop function
setConfig(_AMAX, 1, getvalue(_BLSPEED, 1))
setConfig(_AMAX, 2, getvalue(_BLSPEED, 2))
wait(10)
goto mainloopNext I sent a Serial ~AMAX query. Speed for motor 1 was reported on channel 1, but channel 2 stayed 0. So Microbasic queries for motor speed channel 2 are unsuccessful as well.
Hoping this helps to track down the bug.

There is an issue with earlier versions of the firmware. Try installing the latest from our web site.

As suggested, I\'ve again updated to the latest firmware, and motor 2 is still not reporting speed.
It operates perfectly, which leads me to believe that the wiring is correct.
I downloaded the firmware files from both the product page and the link in the first post in this thread. I unzipped with winrar. In both cases the firmware appears to update successfully. Here\'s the output (identical for both):
Please advise.
