shutdown RFX2411N PA/LNA module

[BIPIN]

Hi,

I am using nRF52832 with S132_V2.0.0 and SDK_11.0.0. In my application i plan to use RFX2411N PA/LNA module. In datasheet of RFX2411N, I found that it can be used in following four mode.

Using sd_ble_opt_set(BLE_COMMON_OPT_PA_LNA, &opt), my application can control TX mode and RX mode automatically. It can also control Bypass mode by MODE pin but How can it control shutdown mode? Beacuse It needs TXEN and RXEN pin low but after calling sd_ble_opt_set, I am not able to set it low. So how can i control this two pin as a GPIO?

I have tried to uninitialize PPI and GPIOTE module but it gives me error.

Thanks, Bipin Patel

So if you don't want to use BLE, so you are not scanning, advertising, connected etc, those TXEN and RXEN pins won't be driven. They should be (and i believe that nordic engineers implemented it like that - have not checked myself) activated only when transmission/reception is in progress. You are observing change of the states on these pins when BLE is NOT used? if yes, that is some major bug up there. But if you want to control transmission/reception only by enabling/disabling PA/LNA, that is not a proper way to save power...
