MSP432 GSM Interface

Other Parts Discussed in Thread: CC3100BOOST, ENERGIA

Hello All

I am trying to do some hobby project where i want to send an SMS and depending on the text the MSP432 must display the message on LCD and set a pin high or low.

Three Scenarios are as below :

1. SMS sent -- > " Turn ON" ---> on LCD display as " Turn on the Lamp" ---> A port on the MSP432 will be set to HIGH as which is connected to relay.

2. SMS sent -- > " Turn OFF" ---> on LCD display as " Turn Off the Lamp" ---> A port on the MSP432 will be set to LOW as which is connected to relay.

3. SMS sent -- > " STATUS" ---> on LCD display as " Current state of relay" ---> MSP432 sends an SMS to the phone number to mentioning about the status.

I have worked and checked on the UART with Interrupt on EUSCI_A0_MODULE. I can hold upto 8 bytes of data.

Can any one suggest some links on similar or help me proceed further.

Thanks

Hi Nanda,

There is a somewhat similar project here: e2e.ti.com/.../how-to-build-a-wi-fi-lamp

Thought I'd throw this idea out there - are you aware of something called Temboo? temboo.com/.../getting-started It has some things to help generate Energia-style code for you to interface your launchpad with a whole different host of other services over the cloud (e.g. twitter, weather, etc). For example, if your project is trying to controlling a light remotely as your description appears to be, you could use the MSP-EXP432P401R Launchpad with the CC3100BOOST boosterpack to interface with wi-fi to the cloud. If you really want to use SMS texts for controlling the lamp, there is a second service called Twilio that Temboo can interface with that would let you send texts from the cloud I believe (but don't know if that one is free) temboo.com/.../send-sms . Alternately, you might be able to control your lamp over Twitter or something temboo.com/.../

Trey German might be a good person to follow on Hackster if you want to see some cool Launchpad projects:

Have fun Making!

Hi Kumar,

I think Temboo will be your easiest solution.

If you are interested in using an actual celluar module your choices are a bit limited but I believe the Adafruit FONA has a pretty straight forward solution: https://www.adafruit.com/fona

You can use their Arduino library with Energia to work with MSP432. Either use Energia IDE or import the Energia sketch in CCS or CCS Cloud.

Thanks Katie and Mark,

Appreciate your suggestions.

I was actually thinking to use SIM 900A GSM module which would be a straight forward solution. Connecting Tx and Rx to the UART of the MSP432 should help but gave a second thought as it might be too costly to afford for a hobby project.

By browsing through for an alternate i found that older Nokia phones can do the trick. It can send the AT commands to the controller but have not got any more information if it is really possible.

Any suggestions??

Thanks
Kumar

Your best bet would be to find either documentation of the AT commands or some sample code. You will just need to hook the nokia signals up to UART on the MSP432. There are examples of how to use UART in Resources explorer or you can use the Serial API in Energia. energia.nu/.../

Thanks Mark

Using MSP432 wanted to do it in CCS. Seems like Energia is a good option but would like to try in CCS with c code .

I have another thread may be you can suggest how to proceed ...
