How to use PCA10040 as Dongle Scanner

Hi Jorgen:

I use nus_collector.py read data but data was lost.

I send 200 bytes data but I only receive 47 bytes.

Data is in hvx_evt.data in function named on_gattc_evt_hvx?

Can I modify it?

Thank you.

Are you using the correct version of pc-ble-driver-py? I would recommend that you post a new case where you describe your setup and environment in detail. That way we can help you debug the issue, without spamming this post.

Hello Jörgen!

I have a similar issue to this, but my error message looks something like this:

robban@:pca20020_s132$ python2.7 nus_collector.py NRF52
	0 : /dev/ttyACM0: 000682995637
 
Enter your choice: 0
Serial port used: /dev/ttyACM0
Traceback (most recent call last):

    error_code=err_code,
pc_ble_driver_py.exceptions.NordicSemiException: Failed to open. Error code: 13

I have tried using the nrfjprog -f nrf52 -e command you recommended above, and my PATH includes the nrfjprog binaries. However I still cannot make it work, and the links to the wrong baudrate and similar issues above seem to be broken?

Also I have tried figuring out where the script actually determines which HEX-files should be written with the nrfconnect to my device, I can't seem to find it.

Would appreciate some help!

OK Jorgen I have put a PATH=$PATH:<MyFolderLocation> and it is working now. I'm able to see all the BLE peripherals on the range. Many thanks.

Do you have the path to nrfjprog binary in your PATH environment variable? Which OS are you using?

Yes I have all the tools on my computer. I think I have to put nrfjprog on a special folder but I do not know which folder. Maybe /usr ?

Do you have nrfjprog installed? You also need J-Link drivers, as described in the section about required drivers and tools.

Hi Jorgen.

I have tried to change the baudrate put 115200 and put 1M on the ble_central_ble_app_uart_c example.

When I change the auto_flash to True on the python script l155 I got this error : pc_ble_driver_py.exceptions.NordicSemiException: nrfjprog not installed

I think I need to change some path somewhere ...

Thanks

Did you flash the connectivity firmware manually? If you have the firmware flashed, but it is using the wrong baudrate, you might get this error. Please try erasing the board using nrfjprog -f nrf52 -e command and let pc-ble-driver-py do the firmware flashing for you. You can also try disabling the MSD when using Linux, some users have experienced similar issues when this is enabled.

Hi Jorgen !!!

Thank you for this pretty cool answer. I tried your script after flashing my PCA10040 with example/ble_central_ble_app_uart_c on SDK 14.1.0 without any changement. I used the command

$ python2.7 nus_collector.py NRF52 /dev/ttyACM0

An this is the log :

Serial port used: /dev/ttyACM0
Traceback (most recent call last):
  File "nus_collector.py", line 196, in <module>
    main(serial_port)
  File "nus_collector.py", line 158, in main
    collector.open()
  File "nus_collector.py", line 73, in open
    self.adapter.driver.open()
  File "/usr/local/lib/python2.7/dist-packages/pc_ble_driver_py/ble_driver.py", line 126, in 
wrapper
    raise NordicSemiException('Failed to {}. Error code: {}'.format(wrapped.__name__, err_code))
pc_ble_driver_py.exceptions.NordicSemiException: Failed to open. Error code: 13

So I still have the problem. Do you have any idea ?

Hi,

I have attached a script based on heart_rate_collector.c, that works with pc-ble-driver-py v0.11.3. The script connects to devices named "Nordic_UART", which is the default in the ble_app_uart example, performs service discovery, enables notifications for custom 128-bit UUID NUS TX char and receive data from NUS. Let me know if you need more help with this!

nus_collector.py

Best regards,

Jørgen
