PA / LNA support in S132

[Aditya Narayan Tripathi]

I am unable to set the PA/LNA Mode on NRF52832 using SDK 14.2 ( Soft Device Version S132 5.0 ) using the Fansttel BT832X SoC.

i have used the exact function on the below link, and I am calling this function straight from the main() handler at the beginning:

https://devzone.nordicsemi.com/b/blog/posts/pa-lna-support-in-s132.

After setting and enabling the given PA/LNA GPIOs i am getting the following error:

err_code = sd_ble_opt_set(BLE_COMMON_OPT_PA_LNA, &opt);

It's returning  error Code 2 above. (BLE_ERROR_INVALID_CONN_HANDLE).

APP_PA_PIN -- (17)For the  the BT832X module, the GPIOs used for PA and LNA are:

APP_LNA_PIN -- (19).

Do let me know if I am missing something. Let me know if you need any further information.

Regards

Aditya

Hi,

Did you enable the softdevice (ble_stack_init) before you called  sd_ble_opt_set(BLE_COMMON_OPT_PA_LNA, &opt);? Error code 0x2 corresponds to NRF_ERROR_SOFTDEVICE_NOT_ENABLED (defined in nrf_error.h).
