Bluetooth Low energy module

Other Parts Discussed in Thread: CC2640, PGA450-Q1

Hello Sir/Madam,

I wanted to know if TI manufactures any board / IC that has a microcontroller and a bluetooth integrated on one. Size is a constraint for me so it will be pereferable if I get an Ic.

Please also suggest me if there is any Bluetooth IC that can be used with Arduino Pro Mini.

Thank You.

CC2640 is a BLE Soc that has ARM cortex-m3 embedded in it. You can try to use it.

Please see the CC2640 FAQ thread as well. Certified modules can be found on the TI BLE wiki.
CC2640 comes in 4x4 QFN package in smallest configuration.

Best wishes

Thank you so much for replying Sir. Can I use this CC2640 to control two ultrasonic transceivers?

Tank you so much Sir. I will surely look into that thread to see if it works for my application.

Yes, you can use CC2640 to control two ultrasonic transciver.

Thank you so much Sir. Can you suggest me some place where I can get to learn how to code this IC. Also can any ultrasonic signal conditioning IC be used with this? Like PGA450-Q1? or it will just increase the number of MCUs used in the operation.

1. You can download and install BLE Stack v2.2 and read SWRU393_CC2640_BLE_Software_Developer's_Guide to learn how to code CC2640.
2. For ultrasonic sensor, you can refer to arduinobasics.blogspot.tw/.../arduinobasics-hc-sr04-ultrasonic-sensor.html

Hi Shivangi Shukla ,

the answer from YiKai Chen is perfect.

I strongly suggest to use his suggestion instead of yours, since yours would imply to design a PCB with that integrated circuit and the one from YiKai Chen gives you the completed design.

It is possible the ultrasoinic sensor works at 5V. You could need also the following to go from 3V to 5V to interface it to CC26x0.

Thank you for your assistance Sir.

Actually HC-SR04 module is very good but I have space constraint and I can use only one Transceiver. The Maxbotix LZ sonars can serve the purpose but they are very costly. So I need to design a PCB where this can be done cheaply.

Please tell if I am thinking i the right direction.
