Very helpful. Good stuff, Håvard! I tested it with the nrf_app_blinky and tested it with nrf_connect(Andriod app) it worked for me !

Thanks for the information , now i am using nRF52832 , the memory of the ic is 512 kB flash/64 kB RAM

how to adjust the RAM in the project. setting (segger)

what is the value we need to put ...

Hi I am new and learning how to merge two files and tried to run this example on the ble_app_blinky example. May I know how to know what number to adjust the RAM size to for blinky as well as any other future projects I want to work on. I tried using RTT viewer but could not derive anything from there.

Thanks for the tutorial.
but what if it return NRF_ERROR_INVALID_PARAM while calling ble_nus_init();
is there anything should be called above service_init();?
or what cause this kind of problem.

i have been stocked in this problem for many days

This was very helpful in adding ble_nus to another example. In my case I added it to ble_app_blinky as an experiment. However, I had previously experimented with ble_app_uart and added the ability to send a large block of data (4KB) in multiple 251 byte chunks at a fairly high rate. If I try that in the modified blinky code (using the same function code), I can send the large block, but the data rate is significantly lower (it seems as if smaller blocks are used some of the time.) I am using the Nordic UART app as the test app in both cases so it's not governed by the app. I modified the NRF_SDH_BLE_GAP_DATA_LENGTH=251, and NRF_SDH_BLE_GATT_MAX_MTU_SIZE=247 to match what was in the ble_app_uart config file.
