TI has 'launched' a multi protocol wireless launchpad.  

It uses the CC2650 chip:  The CC2650 device is a wireless MCU targeting Bluetooth Smart, ZigBee and 6LoWPAN. The CC2650 device contains a 32-bit ARM

Sounds interesting so I ordered one. Obviously a couple of $4.32 MSP432s that I don't really need fell into my basket too.

Interesting.... so this can be used standalone as well as interfaced to another Launchpad. This will really help in development especially since all the pins are now fanned out... the only downside is the lack of sensors, but I'll not miss them.

Yeah this gives us our "BLE BoosterPack" some of us have been clammoring for.  A tad pricey for something that's just going to be a boosterpack for someone, but obviously that's not at all what this is meant to be... as it's a genuine host MCU all by itself.

"Code Composer Studio IDE license included" would that be a cheap way to get a full license or is that just for >16 kB on the CC2650?

From my experience with the sensor tag it is for the CC26xx's only. The size limit comes from the compiler, and the ARM compiler used for the CC26xx's is completely different to the TI MSP430 compiler. For the MSP, GCC is always free and un-restricted. (but does create slightly larger binaries by nature.)

 

There was no key for the sensor-tag, just installing the simplelink compiler comes with no size restrictions.

 

[it's still slightly limited, in that it doesnt support the more expensive (and faster) debuggers, but works perfectly well with the onboard debugger of the launchpad itself.]

Mine just arrived. It looks like a nice board, but the software and documentation seems a little lacking and I'm not getting very far with it.

 

Flash Programmer 2 fails to upgrade the firmware that the documentation suggests is needed. The "SimpleLink Starter" app isn't in either the Apple of Android app stores. The SensorTag version can't see the device. I can see it from my phone but it refuses to pair.

 

I'm just going through the guide here on how to set up a development environment for the SensorTag. I hope that will get me going in the right direction.

Any open licence BLE stack available?

 

http://www.ti.com/tool/ble-stack

 

Not sure about the exact licence, but it's open source/royalty free. But it is also integrated with TI-RTOS. So it's quite a large beast to compile.

Once the stack is setup in a project the API to make use of it is very straightforward.

 

Then there is the fact that the stack itself will be running on the Network processor, and your code will run on the more powerful Application processor. In most of the examples I've worked with they deal with 2 sepeate CCS projects, one for the stack and one for the application.

The BLE team doesn't appear to have released all the software examples quite yet. It seems this is more of a soft launch at the moment. Examples will come available through Resource Explorer in CCS and CCS Cloud (dev.ti.com). In the meantime you can try to adapt the CC2650 SensorTag example code and app to the LaunchPad. Thanks for your patience!

Less pricey, but not exactly a devboard either. Hell not exactly a hobbyist friendly package . . . Personally, I'm realy interested in the SAMB11. But it's not released to public yet, andno idea how much it'll cost . . .

Additionally, I've done a good bit of reading on BLE lately, and have looked into various "things", and have noticed that TI is literally *everywhere*. Most BLE devices seem to have a TI branded chip inside.

 

So I do not mean this as slight or anything of that nature but I'm curious how TI is almost literally in everything BLE. The chips seem great, but the cost is very high when you compare them to the competition. The LED BLE light I got for an Xmas present this year for example costs ~$30 USD. You can bet that has to do largely with the TI BLE chip inside . . .cost wise.

 

EDIT:

 

Additionally( part duex ), You can find BLE<->Serial adapters suchas these: http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2141725.m570.l1313.TR0.TRC0.H0.Xble+serial.TRS0&_nkw=ble+serial&_sacat=0 Based on the CC254x. Which has me confused. Unless that CC254x is really a "clone".

Well, it seems that the "SimpleLink Starter" Android app is finally available. It's still quite SensorTag focused, but does support the CC2650 Launchpad. It also references the as yet unavailable WiFi SensorTag.

 

I've still not done much with the LaunchPad. When Google open-sourced their Thread protocol I thought it might be possible to link a launchpad up to a Nest mesh network, but that doesn't look likely any time soon according to TI employees over on e2e. Even the documentation and support on 6LoWPAN seems lacking for the CC2650 right now.

Yeah my understanding was OpenThread was targeting sub-GHz anyhow (CC26xx is 2.4GHz IIRC)

 

CC1310 will probably be the platform for OpenThread. I have two of the CC1310 LP's, even they feel a little "green" on the examples and code so far. Seems like an awesome chip so far though. Tiva-like peripherals and all.

CC2650 is 2.4GHz. I would assume that OpenThread is independent of the underlying frequency. Not sure why I thought the Nest implementation was using 2.4GHz - probably either a poorly researched article on it or just my assumption.

 

I understand exactly what you mean about it seeming "green". This is the best I've found - a blog by a TI employee but not the easiest to follow. I'm sure he'll do some CC1310 stuff too.

The links below showed up in an email I received from edX .  They lead to a preview from TI for a CC2650 Module BoosterPack that is supposed to be released in time for a course in September.  Of interest, it includes an "Additional CC2650 Module Sample" along with the BoosterPack.
