Does RF affect GPIO24, and vice versa, on the NRF52832?

[Royan]

I have never used the GPIOs near the RF pin (GPIO 22, 23, 24), until my latest project, which I needed to due to pin limitations. It is normal for pins adjacent to RF outputs to be either not connected or grounded. In my current layout (shown below), I am bending the trace for pins 25 to 29 as tight as possible away from pin 30 (RF), but it still means that pin 29 would be near (about 0.2mm) pin 30.

Would the RF pin (pin 30) affect the performance (higher noise) of these GPIOs, particularly GPIO 24 (pin 29), and vice versa (RF affected by fast switching GPIO24)?

If you read the PS, there is chapter 4.3: "GPIO usage restrictions".

There are mutiple pins restricted to low drive and low frequency (<10kHz).

Thanks a lot Turbo. Yup, should have read the datasheet thoroughly. Also just found out that low drive is defined as < 0.5mA.

As long as you follow the GPIO usage restrictions, there's no problem to route it like you do. But you seem to have an extra component in the matching netwotk, the nRF52832 matching network normally looks like this:
