PA and LNA pin in BLE mesh examples

[Domneck]

Hi All,

I'm referring to generic on/off ble mesh example code and we are in the development stage.

I would like to know which pins are used for PA and LNA in the example code and what changes do I need to make if I want to enable it on my custom hardware.

Here is the code snippet from example code: gpiote_setup(&m_gpiote.params.lna_cfg, m_gpiote.params.ppi_ch_id_set);

Thanks in advance.

Hi. 

Have you seen the documentation about adding PA/LNA support?

Hi,

In link I see GPIO pins 25 and 24 are used for PA and LNA but in schematic I'm finding it (in PCA 10056).

And if I want to change in software as per custom hardware how do I do?

And also I checked in debug mode "mesh_pa_lna_gpiote_enable" is the function to enable and it's not called any where in the code and "m_gpiote.enabled" flag is false always.

Regards,

Domneck

There is a code example in the link i sent you. In the guide we are using GPIO pins 24/25, but you are free to change this to any other unused GPIO.

 Did you add a call to the mesh_pa_lna_gpiote_enable() function? 

Point 3. in the guide: sd

Enable the PA/LNA module by calling mesh_pa_lna_gpiote_enable() after the call to mesh_init():

    mesh_pa_lna_gpiote_enable(&m_pa_lna_params);
