about nordic sniffer python API - getList()

[Jones]

Hi,

I tried to use python API to drive the nrf sniffer to capture ble device information by their advertisement packet. I can successfully target a specific ble device by .find("DeviceModelABCD").

But my final target is to capture a specific model of ble device which their device name have same prefix but different suffix. i.e. "DeviceModelABCD", "DeviceModelEFGH". So I tried to use the api .getList() to get a List so that I can check the name one by one to see which are those target devices true name. However, once I run this api, it fail and the error is that "DeviceList instance has no attribute 'getList'".

---

Code:

mySniffer = Sniffer.Sniffer("COM19")

mySniffer.start()

devList = mySniffer.getDevices()

ListOfDev = devList.getList()

---

Since this api is written in the Sniffer api guide, I don't know what have I done wrong.

By the way, is there any other way for me to achieve my target instead of calling this API?

Hi,

The Python script linked in this blog post use a different method for matching the address of the device you want to follow:

tls_dev_addr = [0xde, 0xde, 0x96, 0xdf, 0x92, 0x4a, True]

for _ in range(10):
    time.sleep(1)
    devlist = sniffer.getDevices()
    found_dev = [dev for dev in devlist.devices if dev.address == tls_dev_addr]
    if found_dev:
        follow(sniffer, found_dev[0])
        break

Could you try a similar method for matching the name?

tls_dev_name = "deviceName"

for _ in range(10):
    time.sleep(1)
    devlist = sniffer.getDevices()
    found_dev = [dev for dev in devlist.devices if dev.name == tls_dev_name]
    if found_dev:
        follow(sniffer, found_dev[0])
        break

Or, if you only want to check for a (prefix) part of the name, you could use:

found_dev = [dev for dev in devlist.devices if "prefix" in dev.name]
