NONOS SDK 3.0.3
Calling wifi_set_sleep_type( MODEM_SLEEP_T ) appears to have no effect on the sleep state of the chip. My AP has a DTIM of 1, so I should be seeing ping times vary randomly to over 100 ms. However, the ping times I get are this:

This is not in modem sleep at all.
Has this ever worked properly?
I do not see any bug fixes related to modem sleep for 3.0.4 and 3.0.5.
This is a legacy design, updating to the RTOS SDK is not currently an option.
Is there some other operating condition I need to meet in order for the sleep mode to take effect? Has it ever worked? Are there any examples that show it working?
