Receiving data via 802.15.4 radio

[Strokes]

Hi,

I am familiar with using a bluetooth radio to receive data wirelessly through the serial port using VISA in LabVIEW. However due to the range limitations of my bluetooth radio, I'd like to have a go at receiving date via from an 802.15.4 radio. Has anyone any experience doing something like this and is it possible using VISA and a serial port? Presuming I know the data packet format, it should be ok right..?

Hi Strokes,

Do you plan on buying a third party 802.15.4 wireless device that connects to your computer through the serial port?  What hardware do you intend to use?

I assume you wish to use your existing code that was designed for the Bluetooth dongle. Are you communicating using a serial protocol or Bluetooth protocol (Bluetooth or Serial VIs)?

What is your current setup?  Do you have a Bluetooth device that connects to your PC via serial? What hardware do you have sending and receiving the data?

Have you seen the NI Wireless Sensor Networks and have you thought about Using LabVIEW with TCP/IP and UDP?

Kind Regards

No I plan on using a Shimmer device (see here) which as a 802.15.4 radio on it's circuit board to communicate to a laptop via serial port.

I'm not set on using the existing code as used with the bluetooth radio on the Shimmer, but if it will reduce the workload then yes of course I will. The existing code currently uses serial protocol so I guess I could modify the existing code?

My current setup is: I have a Shimmer (wireless sensor, accelerometer in this case) that has both a bluetooth radio and 802.15.4 radio. Due to my application needs, I would like to transmit data to the serial port via the 802.15.4. There is existing code which allows the Shimmer to communicate with the serial port using Bluetooth radio.

I'm not looking for code or anything, just wanted to know how to go about it and if I could use VISA which I'm fairly familiar with.

Thanks,

Hi Strokes,

I have had a look on the shimmer website at the FAQ.

What radio protocols are available on Shimmer?

Shimmer has two radios: the Bluetooth module supports the Serial Port Protocol. The 802.15.4 radio implements its IEEE physical and link layers; higher-level open-standard network protocols, including several mesh, ad-hoc, and IP protocols (v4 and v6), are implemented in software between the two versions of TinyOS.

From this, I would say that you cannot use origianl serial code because a different protocol is used.

Have you seen the Shimmer LabVIEW Library? It may be useful to you. There is a good manaul here.

Kind Regards
