[joshschmelzle]

Currently FPMS is set to use channel 36 when bringing up profiler.

Lines 219 to 237 in 39f47c4

	if action == "start":
	# set the config file to use params
	cfg_dict = {"channel": "36", "ft_disabled": "False", "he_disabled": "False"}
	self.profiler_ctl_file_update(cfg_dict, config_file)
	elif action == "start_2dot4ghz":
	# set the config file to use params
	cfg_dict = {"channel": "11", "ft_disabled": "False", "he_disabled": "False"}
	self.profiler_ctl_file_update(cfg_dict, config_file)

	# set the config file to use params
	cfg_dict = {"channel": "36", "ft_disabled": "True", "he_disabled": "False"}

	cfg_dict = {"channel": "36", "ft_disabled": "False", "he_disabled": "True"}

Menu options may indicate channel + frequency, but FPMS should set / read frequency (to make it 2.4 / 5 / 6 GHz compatible) from config.ini.
