MSP430FR5994: Using bluetooth low energy to communicate between two msp430FR5994?

Hi,

I want to establish communication between two MSP430FR5994 launchpads using bluetooth low energy. I found out that we have a free software stack [http://www.ti.com/tool/CC256XMSPBTBLESW] for MSP430 devices (Works with any MSP430 MCU with Flash >= 128KB and RAM >= 8KB) for Bluetooth devices that is just the "software" which enables using bluetooth low energy.

Now for the hardware part, we might use CC256x EM boards (CC256XQFNEM or CC2564MODNEM) which can plug directly into boards like
MSP-EXP430F5529
MSP-EXP430F5438
But one thing I am skeptical is that will these devices work with MSP530FR5994. Are these the right devices to use for BLE? What is the difference between? Which one should I order that can be easily interfaced with MSP430Fr5994 launchpads for low power Bluetooth communication. I am sorry for asking such questions, I am new to interfacing MSP430 launchpads with BLE.

Thanks!

Hi Rohit,

The reference provided is not directly compatible with MSP530FR5994 devices. if your requirement is to use BLE only you can refer to CC2640R2F parts and launchpads/boosterpacks.

Hi Sudharshan,

Thanks for the information. My application requires me to do computation on one MSP430FR5994 and then send the results to other msp430fr5994 using BLE. So, as per your suggestion I should be using something like uart to communication data from MSP430FR5994 to CC2640R2F launchpad and then transmit it using BLE and having a CC2640R2F launchpad receiving it and transmitting it using uart to other MSP430FR5994?

Best,

Rohit

Hi Rohit,

I would assign the thread to the BLE expert. They will be able to guide you better

Thanks Sudarshan. Also, I plan to measure the energy of BLE communication. Is there any launchpad that comes with energy trace for that.
