There is a similar case to this one.

Have a look at Hung's answer.

Ok, I already connected the the CPS to a GPIO. The topic is how to drive that pin high in the timeslot when BLE GATT messages are sent, and drive low when BLE mesh messages are sent. I think that this task is very time constrainded, I think that is something for the radio layer, isn't it? is it implemented in the library? I hope to be clear in my explanation. thanks

You need to connect the CPS pin to a GPIO signal to control the mode.

Hi, I took a look at datasheet, and what I want to understand is how to drive CPS pin if I have to swith to 0 when I use mesh, to achieve high range, and to 1 when I use bypass mode to use GATT features.

Hi,

I suggest you take a look at the SKY66112-11 Datasheet. CPS is pin 15, take a look at Table 1. SKY66112-11 Signal Descriptions and Table 6. SKY66112-11 Mode Control Logic.
