Data exchange through UART

[Mihail]

I have nRF8001-DK and Arduino Uno. ble_uart_project_template from nRF8001 SDK for Arduino (Bluetooth_low_energy_for_Arduino_0_5_0_0_RC2) was used. It was used with Master Emulator with nRFUart sample code included. By using this template I can send string from nRFUart and recieve this one in Arduino Serial Monitor. How I can add functionality to send string to nRFUart from Arduino Serial Monitor?

And I can't start with ble_uart_project_modify_setup. nRFUart can't discover nRF8001.

I have modified the ble_uart_project_template sketch to allow the serial monitor of the Arduino to send data from the PC. Set the baud rate to 115200 with Newline. I use the "newline" character '\n' to detect the length of the string before sending it to nRF UART app.

The modified sketch is attached.

Note: The ble_uart_project_modify_setup project is used as an example to recalculate the CRC for a Setup that was manually modifed. The recalculated CRC can then be put into the header file so the Setup can be successfully sent to the nRF8001.

Thank you. I have tried send data from Serial Monitor (SM) of Arduino to Master Emulate (ME) and not seen any changes in UART Tx and UART Rx, but I still can send data from ME to SM.

I am sorry. I was not logged in. Perhaps the reason is that we have to change anything in the profile. Currently I have service named UART over BLE with Characteristics UART Rx with properties WriteWithoutResponse and UART Tx with properties Notify. How I have to change Characteristics to realise your sketch?

I am also using the UART over BLE Service with the UART RX and UART TX Characteristics. You do not have to change any Service or Characteristic. Take the edits that I have done on the ino file that I have attached.

I have tested it with Master Control Panel 3.4.0 and it works well.

When you are using it with Master Control Panel, remember to click "Enable Services", this will subscribe the Master Control Panel to the Notifications. Now you should be able to send data from the SM to the Master Control Panel as well.
