Johan WestlundI haven't looked at devices with propriety mesh protocols as I want it to be open and therefore devices that can be upgraded to the standard when it comes is a big plus. I have also been looking more for dual protocol chips so I don't lock my self to Bluetooth in case integration with home automation is needed where ZigBee has had more time to grow.
| Manufacturer | Model | Price | Avg. power | Connectivity | ADC | ARCH | Comment |
| TI | CC2650 | ~$2.70 | 6.8µA(based on 2540) | BLE, 802.15.4 | >5x12bit | ARM M3+M0 for the communication | Good support, probably BLE mesh in the future, Supports Over-the-Air updates, cheap dev kits |
| Nordic Semiconductor | nRF51822 | ~$2.31 | 5.6µA | BLE | 8x10bit | ARM M0 | |
| NXP | KW40Z | ~$2.06 | BLE, 802.15.4 | 1x16bit? | ARM M0 | I like this one as well, but it have been hard to find information and the dev kits are a lot more expensiver | |
For now the CC2650 looks hard to beat because of the more DIY approach and a lot of support and that from what I have found the only one that will work out of the box without additional ADC and compactors(I want the device to wake up in case of an alarm). This have been a half day research so if there is other SOCs and solutions, feel free to share. :)
