Hi Kevin

As I mentioned, P0.15 is not used in ble_app_uart_pca10040e_s112.hex and does not have a "function" other than being connected to button 3 on the DK (development kit). It is not used at all in the ble_app_uart example.

Best regards,

Simon

Hi Simon,

Sorry, my English is not good.

I use CPU to output high signal and set the pin.

I just want to know function of P0.15 in ble_app_uart_pca10040e_s112.hex.

Because I let P0.15 to be floating, it can't broadcast repeatly via reset signal after first advertising packets closing.

Thanks!

Hi Kevin

I'm afraid I'm still struggling to understand your issue.

[quote user="Kevin.Chuang"]CPU set the pin to become GPIO. Both P021 & P0.15 are setted to H.[/quote]

If you're using the ble_app_uart_pca10040e_s112.hex how are you setting these pins to high/low? The ble_app_uart_pca10040e_s112.hex will not be changed even if you edit the project in an IDE, for example?

P0.21 however, is the reset pin, and should reset the nRF52810 if you press it. Can you try to explain what you'd like to achieve here, as I'm not sure I understand what you want to do here? Do you want to be able to reset the device with P0.15 as well?

Best regards,

Simon

Hi Simon,

Thanks for your supporting!

During period of I use "ble_app_uart_pca10040e_s112.hex" (SDK nRF5_SDK_17.0.0_9d13099), I try the following test.

P0.21 & P0.15 connect to CPU, CPU set the pin to become GPIO. Both P021 & P0.15 are setted to H.

Test 1：When advertising packets close, we try to give command to let NRF52810 broadcast repeatly.(Command include P0.21 Low pulse(H→L→H), P0.15 keep H) NRF52810 broadcast repeatly. We can use App_nRF Connect to search "Nordic_UART".

Test 2：We disconnect P0.15 with CPU.When advertising packets close, we try to give command to let NRF52810 broadcast repeatly.(Command include P0.21 Low pulse(H→L→H) NRF52810 can't broadcast repeatly. We can't use App_nRF Connect to search "Nordic_UART".

So i want to know function of P0.15 in ble_app_uart_pca10040e_s112.hex?

Thanks!

Is there a specific reason you're asking? P0.15 shouldn't be defined at all in the pca10040e ble_app_uart example (SDK v17.0.2 at least).

Best regards,

Simon
