Connectivity code

[Youngjun]

Hi,

I'm using pc-ble-driver-py.

I bought the nrf52832 dongle.

The problem is uart pin number of dongle.

The pins of my dongle and the pins of the hex file are different.

So, i modified connectivity project in SDK14.2.0.

#define RX_PIN_NUMBER 6  //8
#define TX_PIN_NUMBER 5  //6
#define CTS_PIN_NUMBER 8  //7
#define RTS_PIN_NUMBER 7 //5

And, i used softdevice 5.1.0 ( hex string = 0xa5)

When i use above version, i got message in pc-ble-driver-py

Unknown Nordic Semiconductor vendor specific packet received
Failed to receive response for command
Failed to ble_cfg_set. Error code: NRF_ERROR_SD_RPC_SEND

I think version of softdevice match the latest connectivity file in pc-ble-driver-py github.

• connectivity_4.1.1_1m_with_s132_5.1.0.hex

How can i modify uart pin?

I also used sdk15.3.0 and softdevice6.1.1

Hi,

I bought the nrf52832 dongle

Which dongle is this? Nordic only have dongles with nRF51 and nRF52840 chips.

It is not possible to use the connectivity FW directly from the SDK, it requires some additional changes in order to work with pc-ble-driver(-py): Compiling connectivity HEX files

You can also find the patch here, and apply this to an unmodified SDK directory.

Best regards,
Jørgen

hi,

I bought this dongle in aliexpress.

And, this is noy compatible with connectivity.

I can't modify pin number physically.

When i saw the pc-ble-driver, i couldn't find pin definition in project.

Where can i modify pin number in pc-ble-py project?

Best regards,

Youngjun

It is not possible to change the pins in the pc-ble-driver project, you need to modify this in the connectivity FW, which is what's running on the nRF52832 chip itself. 

After patching the SDK, you should use the project found in 'examples\connectivity\ble_connectivity\pca10040\ser_s132v5_hci'. The UART pins are taken from the pca10040.h board header file.

Then, i have to modify connectivity in sdk and make connectivity.hex like pc-ble-driver page.

Thanks.
