requesting help with meta command script

tekstyle

i am trying to write a command in config.g where it will write to another file and run it upon start up. the part that i can't wrap my mind around is I need the script to basically turn on access point mode upon start up and if I turn off the machine and turn it back on, it will turn off access point mode and turn on client mode. essentially, I need it to flip-flop everytime i turn off and on the machine. any help would be great. So far, this is what I came up with. can someone please check these and see if it will work?

;/sys/PRINTCODE/globalwifi.g

global wifi=AP ;assign global var to globalwifi.g

;config.g

M98 P"/sys/PRINTCODE/globalwifi.g" ;call globalwifi.g to define wifi variable
M98 P"/sys/PRINTCODE/network.g" ;call network.g macro

;/sys/PRINTCODE/network.g

if global.wifi=AP
	M552 S-1	;disable networking
	G4 S4		; wait 4 sec
	M552 S0		; turn off wifi module
	M552 S1		; turn on client mode
	M28 "/sys/PRINTCODE/globalwifi.g"	start writing file
	global wifi=C
	M29		;stop writing to file
	G4 s4		; wait 4 sec
	set global.wifi=C
if global.wifi=C
	M552 S-1	;disable networking
	G4 S4		; wait 4 sec
	M552 S0		; turn off wifi module
	M552 S2		; turn on AP mode
	M28 "/sys/PRINTCODE/globalwifi.g"	start writing file
	global wifi=AP
	M29		;stop writing to file
	G4 s4		; wait 4 sec
	set global.wifi=AP

You need an elif in your macro.
Otherwise the second IF will reverse the first because you've just set the global to C.
Edit: ~~Also you forgot to use SET in a couple of spots~~
Probably deliberate as you may not be creating the global in config.g

if global.wifi=AP
	M552 S-1	;disable networking
	G4 S4		; wait 4 sec
	M552 S0		; turn off wifi module
	M552 S1		; turn on client mode
	M28 "/sys/PRINTCODE/globalwifi.g"	start writing file
	global wifi=C
	M29		;stop writing to file
	G4 s4		; wait 4 sec
	set global.wifi=C
elif global.wifi=C
	M552 S-1	;disable networking
	G4 S4		; wait 4 sec
	M552 S0		; turn off wifi module
	M552 S2		; turn on AP mode
	M28 "/sys/PRINTCODE/globalwifi.g"	start writing file
	global wifi=AP
	M29		;stop writing to file
	G4 s4		; wait 4 sec
	set global.wifi=AP

You might also consider checking for the existence of the global so it only runs the code on a cold start, and not if you run M98 P"0:\sys\config.g"

if !exists(global.wifi)
    M98 P"/sys/PRINTCODE/globalwifi.g" ;call globalwifi.g to define wifi variable
    M98 P"/sys/PRINTCODE/network.g" ;call network.g macro

I never actually knew how to use an "elif" in my coding. it always returned errors when testing. I will implement your changes and see how it goes as I am not at my machine now.

You are correct in having no SET in my config. I purposefully put those in globalwifi.g and call globalwifi.g from config.g upon boot up. the reason being I do not want to overwhelm my config file with too much stuff when I need to refer back to do modifications to it.

@owend said in requesting help with meta command script:

    M98 P"/sys/PRINTCODE/network.g" ;call network.g macro

just out of curiosity, upon boot up, the only way to define global wifi is with the globalwifi.g file. is this condition necessary if I do not have any global wifi = nnn anywhere in my config? the way I currently have it, global wifi = nn is evoked when globalwifi.g is called during startup where nn can be C or AP depending on what was last written. the config.g will just call for globalwifi.g and it should flip-flop with every start up.

@tekstyle
The way you have it is fine.
The check for the globals existence will just avert the swapping of modes if you just re-run config.g instead of doing a system restart

@owend Thank you for your support. also learned something new!
