I’ve a HE910-D, firmware 12.00.022, when issuing a CFUN=0 command and then bringing RTS high then low, CTS is still high, so it’s not exiting power save mode. (the same code works on a GM862) I’ve read through the HE910 software user guide and I don’t see that I need to do anything different. Any tips on what I’m doing wrong?
For HE910 try:
AT+CFUN=5 works in combination with DTR line to enter/exit from power saving mode.While the AT+CFUN=0 can be used in combination with VBUS to enter/exit from this mode without any other serial line activity.
