Which GPIOTE channels are used in s140?

[irarykim]

Hi, 

I am using s140 v7.0.1 for nRF52840.

I found if I configure NRF_GPIOTE->CONFIG[0], then BLE will not work.

Which GPIOTE channels are used in s140?

Thank you.

Hi,

The softdevice does not use any GPIOTE channels.

• What are the symptoms of "BLE not working"?
• Did you make any other changes at the same time that could have caused this?
• What is the exact code you added that caused the issue?

Best regards,
Jørgen

That issue is about the radio driver in Zephyr, it is not related to the softdevice. If you are using nRF5 SDK (which I assume you are, since you are using s140 softdevice), that is not relevant.

Which pin are you configuring for use with GPIOTE?

Yes, I am using nRF5 SDK. But sometimes I directly use registers.

The pin is P0.08.

After I changed the channel from 0 to 4, BLE Tx worked. So I believed the comment in Zephyr link.

I should see if I used channel 0 in other part of my firmware.
