How to use Ring indicator in WP7600

1

hi, im trying to wake up my sierra wp76 from edrx mode when i receive an SMS and i saw that there is a Ring indicator gpiout that goes up when i receive one but i dont know how to access to him, does anyone know how to do it?

2

you need to see the AT command guide on the following commands:



AT!RIOWNER

at+WRID

AT+WWAKESET
3

thank you! do you know if there is a way to access physically to the pin RI?

4

you can see here:

5

nice, now i have /sys/class/gpio/gpioRI/
but the value is always 0, also if i received a call or an sms

6

if you set “AT!RIOWNER=1”, it is just used as a GPIO pin in your linux system. (e.g. GPIO output pin or GPIO input pin)

I guess you need to try “AT!RIOWNER=0” and configure AT+WWAKESET for the voice call or sms indicator

7

my objective is to enter in a Low power mode and then when i receive an sms wake up… if i configure the gpioRI the value is never changing also when im receiving sms.

also i tried to do AT!RIOWNER=0 and then AT+WWAKESET=16 and UART_RI stay high. i tried echo mem > /sys/class/autosuspend and send an sms and im not waking up (the line is still up)

8

A bit confused…..

How is this objective related to ring indicator pin???

Btw, you can have a look on “wakehosten" in at! custom command

9

From what I understand, I can configure RI to go high when I receive a text message. This would allow me to use that signal to wake up from low power mode. If you have a better idea, I’d love to hear it.

So it is working now on your side, right?

11

not really, to do export to gpioRI i have to do at!riowner=1 but if i do that im not receiving a signal when i receive an sms

12

How about at!riowner=0 and AT+WWAKESET=14

Did you see the ring indicator pin toggled when receiving sms?

13

no, its the same. it doesnt change

14

How about receiving voice call

Which firmware version are you using?

15

okay i saw right now that if receive a voice call gpioRI change from 0 to 1 but then when the call finish, does not come back to 0

16

Then how about you dial another voice call to it?

I just found that we should use AT+WWAKESET=20 for voice call and incoming SMS.

With WP7608 FW R16.3, here I just made a test with the following setting, I can see the RI pin toggled for voice call and incoming SMS ( and the pin will go back to 1.8V after toggled):

at!riowner=0 

AT+WWAKESET=20

at+wrid=3000
