UART/Serial Port Emulation over BLE seems not running

Hello guys,

I've a PCA10040 connected to my laptop.

It works fine with all the .hex BLE template example in the nordic SDK except with the UART example.

After download the ble_app_uart_pca10040_s132.hex I expected the device is advertising with the device name "Nordic_UART" and LED 1 is blinking (period 2 sec, duty cycle: 10%).

I also started Putty Emu Terminal 

Nothing happen!

The LED1 on the PCA  is stady ON.

Any idea or suggestions?

Of course as said earlier, the other BLE example as ble_app_template_pca10040_s132.hex   works fine.

  • Hello Amanda,

    sorry for late reply to your message.

    I solved the issue.

    The "ble_app_uart_pca10040_s132" its running on the pca10040.

    One of the last issue I've experienced is the error "error on writing characteristics (128)" when I attempt to write a value by using the nRFtoolbox' uart app.

    But this error seems to be related to the Android on my specific mobile, however changing mobile the issue disappear and all works fine.

    Thanks for your support.
