I am having issues with bringing the robot out of its sleep or off mode. Seems it goes into sleep mode when there is no activity for about 4 minutes. I am using the i-Robot Create 2 serial cable. When it is in its sleep mode I try removing the cable end plugged into robot and connect jumper wire between pins 5 and 6 on the robot 7 pin connector for a brief time period. This effectively shorts the BRC pin to GND for a short period of time ( less than 1 second). Then I reconnect the serial port cable into the robot 7 pin connector and try giving the robot a command but no go. I have also read that commands 173 and 173 173 can help with this issue but I may be mistaken. Any help on this is very much appreciated !!!! Rick
The Create 2 cable will wake the robot when plugged in without any modifications. 173 is the 'stop' command that stops the OI. It does not do anything if the robot is sleeping. Also, in the OI Manual it states the robot goes into sleep every 5 minutes unless in full or safe mode.
I suspect you may have a bad cable. Have you verified that the pin is changing level on the end of the Mini-DIN (with a voltmeter)? If it is not, and you are using an iRobot cable, contact [email protected] referencing this post.
