Flashed ble central code not working after power reset in development board

[Manjunath b a]

Hi all, actually I am able to flash ble cental code to development board, and can able to connect and send data trough nrf connect app.

But my issue is, when the power to board is reset , I am not able to connect ble central using nrf connect app.

Guessing code is not storing in flashed memory

Using: SDK 17.0.2, nrf52832.   S132

Hi, 

I am able to flash ble cental code to development board, and can able to connect and send data trough nrf connect app.

How does the central app connect to nRF Connect? Does nRF Connect run as a service server? What is the application? Why does it need to run as central to send data to nRF Connect? Are you able to provide an nRF Connect log regarding this part?

From the log, seems your central device tries to scan and connect to Nordic_Blinky (17B9553BED6A). Is your target?

Disconnect reason 0x13 (BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION) indicates that the remote user terminated the connection. So if you see this on the nRF, it indicates that the phone decided to disconnect for some reason. 

Disconnect reason 0x3E (BLE_HCI_CONN_FAILED_TO_BE_ESTABLISHED) means connection failed to be established.

Do you implement the custom service server on nRF connect app?

A sniffer trace will be useful in order to understand more.
