I use nRF52832, sdk17.
First of all, during the sample, you want to implement central using "ble_app_out_c" in the "ble_central" file.
Central wants to connect peripheral address.
"ble_app_uart_c" has no such method.
"ble_app_gatts" has a peripheral address connection method.
However, if you refer to both codes, they don't work.
What's the reason?
Added function "scan_filters_set" among "ble_app_gatts" to file "ble_app_uart_c".
