Help me for Simple way for Transmitter send data to Receiver betwen NRF51822.

Help me for transfer any data between two nrf51822.

1. i already tested example ble_app_uart for connecting nrf51822 to my smartphone (my smartphone use NRFconnect app), and it's work only when i transfer data from my smartphone to nrf51822 (i'm using USB to TTL for serial nrf51822 and arduino serial monitor for see result), but when i send data from serial monitor nothing appear on my smartphone.
2. some forum say that if you want to connect bettwen two nrf51822 you need to use example library ble_app_uart for Central and ble_app_uart_c for peripherals, but nothing appear in my serial monitor. but i feel that two nrf are connected because i can't find any BLE nordic anymore in my smartphone (i use NRFConnect).

3. do i have to edit the example code ble_app_uart_c to sendding any data to central nrf51822??

4. i also use S130 SoftDevice
5. for ble_app_uart
6. For ble_app_uart_c
   
7. For scaning
8. For Serial Monitor

Hi,

Once the ble_app_uart peripheral and ble_app_uart_c (client) central are connected you need to write data to the serial monitor for that data to be sent to the peer, see description here: Testing

1. for sending data from smartphone(Serial Bluetooth App) to nrf51822 then to the PC (by usbTTL Baudrate 115200) now is working both with reciver and transmitter between two device.
2. my next problem is ble_app_uart from diferent Nrf51822 not want to respond "exit" comand when i send "Q" or "q" from serial monitor (according from example ble_app_uart) my question is that my seeting for read/memory is wrong or not? or another of my setting. i'm using diferent debuger STLink V2 for flashing program.

2. Not sure I understand why this should be related to the memory setting? Did you try to debug the project to see what happens when you send the "q" / exit program?

i already solve this problem after meditating on the code for a month. i also already connect two nrf51822 via BLE. Thank You!!!..
