MAGPIO pins state during modem off?

[uknoblic]

Once the modem is turned off (e.g. using at+cfun=0) - what will be the state of the MAGPIO pins? Will they be pulled to GND or will they float?

Thanks

Ulf

P.S. The same question counts for the COEX pins.

Hello Ulf,

When you are in eDRX mode, the MAGPIO pins will go low when the radio is not in use. This previous case https://devzone.nordicsemi.com/support/253105 may help you.

Thanks.

Hi Kazi, the link you have attached seems to be broken :-(

Hello Ulf,

Sorry it was a private case. The MAGPIO pins goes to '0' because an LDO in the nRF91 is turned off by the modem when the modem goes to sleep; regardless of PSM or eDRX mood. This is for saving power.
