Looks like 18 is due to:

#define NRF_ERROR_CONN_COUNT                  (NRF_ERROR_BASE_NUM + 18) ///< Maximum connection count exceeded.

What is NRF_SDH_BLE_CENTRAL_LINK_COUNT set to?

Looks like the ble_app_uart use the softdevice api directly (and thereby need to encode data manually), while the ble_app_blinky use the advertisement module (which wrap around encoding of data and softdevice calls). I think using the advertisement module may be the preferred.

Best regards,

i have used the ble_app_hrs and ble_app_uart examples. I have examined the one you requested and i may have had a reverse of code lines. but now i am getting a connecting error NRF_BLE_SCAN_EVT_CONNECTING_ERROR. the errror returned is 18 but i cannot find what this code is for on the website.

Reviewing the ble_app_blinky they have advertising parameters but ble_app_uart does not. what is the purpose of the paramters and why does one use and the other does not

Also the blinky app also does ble_adv_encode whereas uart does not. What is reason

Have you studied these two examples that should do what you want to do:

peripheral: \examples\ble_peripheral\ble_app_blinky
central: \examples\ble_central\ble_app_blinky_c
