    Using BLE pa_en on  CYBLE_214015 module

    PeSw_2288441

      Hi

       

      I would like to used the BLE pa_en functionality on a CYBLE_214015 module to trigger an interrupt.

      Is there anyway to achieve this? (See attached project for my attempt)

       

      Regards

      Pete

          Hello Pete,

           

          The module CYBLE214015 don't have an integrated Power Amplifier/Low Noise Amplifier to allow for extended communication.

           

          Thanks,

            Hi P

             

            Thanks for responding

             

            I realize the CYBLE214015 doesn't have a PA/LNA or an external connection to P5[0].

            As mentioned in the post I don't want to use the pa_en output to drive an external device, I wish to trigger an interrupt from it.

             

            As the attach project shows Ive attempted to connect the pa_en to a pin component to get the interrupt. This doesn't build due to the CYBLE214015 not having the required P5[0] defined, which is the only pin the fitter will assign to pa_en.

             

            However, the schematic for CYBLE214015 shows the PSoC used (CY8C4248FNI-BL593) does have a P5[0], its just not connected to anything. Therefore, it would seem, the restriction to getting this project to build is just the lack of P5[0] being defined/enabled somewhere in the firmware.

             

            Is there some way to add/enable P5[0] to the CYBLE214015 definition?

             

            An alternative option would be to connect pa_en to an internal component, which can generate an interrupt, that the fitter will not attempt to assign to P5[0], ie not a pin. So far I haven't found anything that is compatible with the pa_en output and can get past the fitters requirement to connect pa_en to P5[0].

             

            Regards

            Pete

              Hello Pete,

               

              The pin P5[0] is not connected for CYBLE214015 module so it is not possible to use pa_en. Please see page no.14 in the BLE component datasheet where it was mentioned that the power amplifier enable (pa_en) output allows you to connect a high active external power amplifier to the device. This output can be routed to the P5[0] digital output pin only.

               

              Thanks,

              P Yugandhar.
