BLE_UART example and UART Driver

[NikTheNordicUser]

Hi good evening,

i am working on a project that requires ble transmission between 2NRF52dks and one of them is connected to a PC and apart from receiving data from another nrf52 and outputting the data serially, I require PWM and UART (using drivers) in order to control a motor RPM speed depending on user inputs, is it possible to combine them all together. I have already coded the pwm and Uart and they work well but i did not integrate this to the ble_app_uart_c and before i do so i wanted to see if it is possible and if so maybe i get some help on how to properly do it.

thanks

best regards

Yes: NUS + PWM + UART: https://devzone.nordicsemi.com/community/f/wireless-forum/69754/nrf52-ble-christmas-tree

For the BLE, start with the NUS example from the SDK. Get that going, and understand how it works.

Then merge your PWM & UART into that.

Ok thanks for the fast response ill have a go at it

hi i tried it and it didnt really work but it could be due to code placement , do I but the uart and pwm functions under the ble ?

or the other way around

is it possible to maybe share your code of the Christmas tree ?

can u hep me ?

Hi Nikolai

You mentioned you were using the ble_app_uart_c example as reference?

This example already has the UART enabled, so adding this should not be necessary. 

I modified the example to also include PWM, so you can see how this is done. 

The example here (just unzip to \nRF5_SDK_17.0.2_d674dde\examples\ble_central):

ble_app_uart_c_pwm.zip

Patch file here, if you just want to see what I changed:
