Not sure I understand what the question is. You dont need to manually turn on the channels since there will be on by default, and call config_board with command from openbci docs between prepare_session and start_stream |

board.config_board("]") and nothing else, I dont understand why you are enabling each channel with some settings and what you are trying to test |

for openbci specific commands and testing protocol it can be better to ask at their forum since I am not an expert in it |

Test Signal Control Commands
0 - = p [ ]
Turn all available channels on, and connect them to internal test signal. These are useful for self test and calibration. For example, you can measure the internal noise by sending 0 which connects all inputs to an internal GND. If streaming, the stream will be stopped, the proper registers set on the ADS1299, and the stream will be resumed.
0 Connect to internal GND (VDD - VSS)
= Connect to test signal 1xAmplitude, fast pulse
p Connect to DC signal
[ Connect to test signal 2xAmplitude, slow pulse
] Connect to test signal 2xAmplitude, fast pulse
Note: Not all possible internal test connections are implemented here
returns If not streaming, returns Success: Configured internal test signal.$$$, if streaming, there is no confirmation.
