Hey,

I want to use MC-WP7607 with my board. at the moment, I check pinning of module to validate my uses cases. There is some misunderstanding on WP76xx MiniCard Accessory Board - Product Technical Specification. On pinnout section, I don’t understand the WP gpio association of mpci express pin :

pin 3 -\> GPIO 1 or GPIO 28  
pin 5 -\> GPIO 2 or GPIO 29  
pin 44 -\> GPIO 3 or GPIO 30  
pin 46 -\> GPIO 21 or GPIO 31

More over, on Figure 2-1 Accessory Board Architecture Overview, there is reset signal between PCIE interface and WP module. on the pinout section, pin 33 seems to link with RESET but it’s marked as NC on signal column. Can I use pin 33 to do electric reset ? Pin 33 is it link to RESET\_IN\_N signal of WP module ?

Can you clarify the pinout please ?

I don’t find schematic resource on your site. Where can I find it ?

Thanks,  
Ben

Hi benjamin.nativel

Customer-defined external switch control for multiple antennas.  
These pins can be configured for use as GPIOs using +WIOCFG

**GPIO Configuration (+WIOCFG)**

Configure a specific GPIO (I/O port) for one of the following uses (indicated by the   
parameter):  
**•** GPIO, accessible via AT commands ( = 4)  
**•** Usage by the embedded Linux host ( = 16)  
**•** Deallocate port ( = 0)  
**•** Antenna select using GPIOs 28–31 ( = 0, then !ANTSEL can be used)

**5.4 Tx Power Control**

GPIO control via !SARGPIO command (see [1] AirPrime WP8548/WP75xx/

WP76xx/WP77xx AT Command Reference)—Set an unallocated external GPIO  
to control SAR. (Available GPIOs are ANT\_CNTL0:2 (correspond to WP76xx  
GPIO28–30) and GPIO21.)

**5.7 General Purpose Input/Output (GPIO)**

The AirPrime WP76xx Accessory Board defines several GPIOs for customer use, as  
described

Pin numbers 3, 5, and 44 map to the WP module’s GPIO28, GPIO29, and  
GPIO30, respectively. References to GPIOs in [1] AirPrime WP8548/WP75xx/WP76xx/  
WP77xx AT Command Reference use the WP module pin identifications.

The AirPrime WP76xx Accessory Board provides three output signals that can be  
used for host designs that incorporate tunable antennas

**5.12 Antenna Control**  
The AirPrime WP76xx Accessory Board provides three output signals that can be  
used for host designs that incorporate tunable antennas.

Signal direction with respect to module.  
Examples: ANT\_CNTL0 (pin 153 ) is an output from the module to the host

Yes, it is.

Thanks for your answer.

In section 5.7 GPIO of Accessory Product technical specification, there is followed table

 ![Capture du 2020-03-25 15-33-23](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/a/a758b391e715bbe1d4a77f5fd7df9586661280e3.png)

Like you can see, mcpi express pins have both GPIO assignments. What is the good assignment ?

Thanks  
Ben

Hi benjamin.nativel

Please refer to section 9.1 Pin Description

 ![PIN](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/6/60d95c19794a16f8f82bb8143c02a6e525b3425f.png)

You can use +WIOCFG command to configure GPIO

Configure a specific GPIO (I/O port) for one of the following uses (indicated by the  
parameter):  
**•** GPIO, accessible via AT commands ( = 4)  
**•** Usage by the embedded Linux host ( = 16)  
**•** Deallocate port ( = 0)  
**•** ANT\_CNTL0 - ANT\_CNTL2, GPIO21 is set by AT!ANTSEL using GPIO\_28 to GPIO\_31 respectively

I understand that AT command WIOCFG allow to select alternate function of one GPIO. I understand that if I want to selection antenna I must to deallocate port of GPIO 28-31. For instance, If I want to use one GPIO by the embedded Host for toggle one externally LED via pin 46 of mPci express connector. What is it the GPIO that I must configure with AT command WIOCFG ? (GPIO 21 or GPIO 31)

In section 9.1, there is both assignment.

You must configure GPIO21 with AT command to use one GPIO by the embedded Linux host.  
AT+WIOCFG=21,16,0,0,1,0,0

GPIO31 is being used as the selected antenna.

It’s clear now. So on electric circuit, pin 46 is link to GPIO 21 and 31. Can I have acces to schematic of MC-WP7607 ?
