CC2540 - Other learning resources + some questions

Cong Nguyen

Other Parts Discussed in Thread: CC2540

Hi, I just got started with Bluetooth LE and picked up the CC2540 mini development kit. So far, I am overwhelmed with the documentation. I have read through TI CC254x developer guide, LPRF San Diego's BLE Deep Dive slides and BLE Tech Day 2011 presentation slides; and I am still unable to figure out where to start with writing a firmware.

Are there other learning resources available? Maybe something more in the form of a walkthrough/tutorial, a flowchart listing the steps needed to develop a firmware? There are a lot of application notes and labs in the MSP430 area but these are scarce for CC2540. It would be great if TI can provide more resources.

I think there's a mistake in the BLE SDK 1.4 guide. In section 3.3.3, according to the guide, GAP_DeviceInit is somewhere in peripheral.c, but it's not.

Thanks in advance.

Hello Cong,

Unfortunately there is no book available that outlines the CC254x and the TI BLE Stack...yet.

You have covered the basic intro material and should start looking at the sample applications. The Samples Applications Guide swru297 can be found here: http://www.ti.com/lit/pdf/swru297

Another helpful resource is the techBasic website that details BLE from the iOS side. This should bring all the concepts together for you.

The forum is filled with answers to questions you will have when you start playing with the code. Search through it along with the web and you will be able to create applications of your own in a short period of time.

Don't forget to visit the BLE-wiki for sample code, documents and other resources. http://processors.wiki.ti.com/index.php/Category:BluetoothLE

Thanks,

Best way to start is with the sample applications provided in TI's distribution; pick the one closest to your desired application. If you're not sure, start with the simple peripheral project.

Run the sample application on the 254x and connect to it using BTool on PC with TI USB dongle or connect from iOS/Android using one of the many (free) BLE developer apps.

For your first application, start by modifying one of sample projects rather than trying to write everything from scratch.
