Other Parts Discussed in Thread: MSP430F2274, SIMPLICITI

hi, im using MSP430F2274 in ez430-RF2500 module with code composer studio V4.  i did several example programs related to msp430F2274 controller which are working perfectly...so now i am working on the wireless temperature sensor demo code. .after following the steps in readme  document i successfully  build the project ..but when coming to the debug part ..it is not detecting the end device and continously blinking the two leds (red and green ) and  going in critical section ...in hyperterminal it is constantly displaying the access point temperature and it is unable to detect the end device and access it..

 

could any one please resolve my problem .....and explain the working of simpliciti network...please could any one reslove this....

 

thank you

    Are you building and programming both an Access Point and an End Device?

    Typically when behavior as you are describing occurs is due to both devices having the same address.  There needs to be unique addresses for every node on a network.  Secondly, the Wireless Sensor Demo needs a Access Point (with Data hub) and an End Point.  Programming both devices as End Points won't be appropriate for this specific demo.

    SimpliciTI itself will support 2 End Devices talking to each other as peers, but there is an example of this in the SimpliciTI download itself.

    hi, thank you brandon Azbell,

     i have programmed only Access point, the end device is already having code in it . so i thought no need to program again ...is there any problem with that and when i try to connect the end device with another working Access point then it is working well with that...so what could be the problem....

     

    thank u 4 ur input

    I would suggest going through the steps to configure, build and download both the End Device and Access Point.  The reasons are 1) paranoia and 2) ensuring that both the Access Point and End Device are using the same LINK_TOKEN, etc.

    thank you ...its working perfectly....but i have a small doubt in this ..i think it is measuring rough temperature not an actual temperature...if want to configure the sensor for actual temperature readings ..what value i need to put in INCH register...in ADC...

     

    thank you so much.....

    It is good to hear you have communication working now.

    I would ask that you post your new question on a new post, in an effort to not clutter up this thread.  Jumping on with additional questions skews the discussion and makes it difficult for others, that may run into similar issues you just faced, to find the answers they need.
