pc-ble-driver-py NRF52 DK "No Response From Device"

[andyknitt]

I'm attempting to use pc-ble-driver-py on Windows with an NRF52 DK (PCA10040) and running into the error shown below.  Using the Heart Rate Collector example, the COM port is able to be opened but the NRF52 doesn't seem to respond.

Here is what I've done so far:

• Installed pc-ble-driver-py using pip3 (Python 3.8)
• Used the nRF Connect desktop app to flash the hex file provided as part of the pip installation to the nRF52 DK:
  • D:\Python38\Lib\site-packages\pc_ble_driver_py\hex\sd_api_v5\connectivity_4.1.4_usb_with_s132_5.1.0.hex
  • 

Are there additional steps required to get this working that I've missed?  Any advice is appreciated.

Hi,

The connectivity_4.1.2_usb_with_s132_5.1.0.hex is for the nRF52840 dongle (which has USB). For the nRF52832, you need to use connectivity_4.1.2_1m_with_s132_5.1.0.hex, where UART is the transport (then the onboard debugger on the DK acts as a USB-UART bridge).

That did the trick, working now, thanks!
