Python Example of pc-ble-driver-py Running with an Error

[wliao]

Hi,

We are trying to implement a laptop / PC based BLE peripheral using Python and nRF52840 Dongle. We installed pc-ble-driver-py and nrf-ble-driver per the instruction. The nRF52840 dongle was also reprogrammed with the firmware s140_nrf52_6.1.1_softdevice.hex.

When we ran the example code advertising.py, there was a timeout error popped up at the function call: driver.open(). See the screenshot below. 

Also noticed that the red LED on the dongle always blinks slowly after programmed.

Please help identify what the root-cause of this error is?

Thanks!

Hi,

You need to use connectivity_4.1.4_usb_for_s132_5.1.0.hex. See this post for more.

Hi Einar,

I tried both connectivity_4.1.4_usb_with_s132_5.1.0.hex and connectivity_4.1.4_usb_for_s132_5.1.0.hex to program the dongle using nRF connect programmer, but the red LED still keeps blinking after the programming and Python example failed the same way as before.

Hi,

You need to use a file that includes the SoftDevice, or add it yourself. You can use the attached hex file (extract the zip), and that should work out of the box. connectivity_4.1.4_usb_with_s132_5.1.0.zip

That works, thanks!
