BLE and Low Level Development / SimbleeCom vs NRF Open Mesh vs BLE mesh
« on: December 01, 2016, 12:37:40 PM »
While BLE Mesh is about to debut soon (not dependent on Bluetooth Core 5.0) , both SimbleeCom and NRF Open Mesh are supporting unlimited of devices.
NRF Open Mesh is considered connection-less, theoretical limit is perhaps 500 devices. Latency is based on latency per hop you set.
SimbleeCom: unlimited connection, 3ms latency.

Developer's questions:
1. Which is more superior e.g. maximum connection, latency by comparison,development time? Or why should one consider SimbleeCom vs the others?
2. Develop now or wait for official Bluetooth Mesh? I supposed how soon your customer wants it.
3. Based on SimbleeCom & NRF Open Mesh, how is the compatibility and migration toward official Bluetooth Mesh? I supposed the consideration is interoperability with upcoming Bluetooth Mesh products if a product choose to do so. Sometimes, you wonder just OTA DFU will help to upgrade to support that. Btw, Bluetooth mesh is meant to support 4.0 as well.

Just for discussion. Of course, those who have experienced Open Mesh and SimbleeCom development can tell more about the differences.

BLE and Low Level Development / Re: Simblee soft device Nordic SDK

Hi Nelson,
  Which version of S110 stack? Is it the same as RFduino? I tried to compile using the same RFduino one but doesn't seem to work. The S110 on RFduino one works and can call the BLE API on RFduino.

You may want to check out Simblee Cloud.

Getting Started / Platform IO: Web IDE with OTA
« on: November 24, 2016, 01:43:15 PM »
Platform IO provides a web IDE for RFduino development. It is said to provide OTA update as well. I haven't tested it out. It is said the compilation time is much faster than Arduino IDE.

Interesting Uses & Applications / Blynk
« on: November 24, 2016, 01:24:03 PM »
If you are spending time developing SimbleeForMobile native UI or Evothings UI, you might find that Blynk is even more efficient than that. For very simple UI, you can achieve that like it said ~5 mins. It is available free in both Android and IOS. If you need more UI, you need to pay in-app store to do that. And, if you publish your app into app store by paying another price, you can roll into both IOS and Andriod very quickly. 

The limitation would only be the UI they provided. If you need very complicated UI, then you would go back to those two that I mentioned. But for very rapid development for a proof of concept, this fits in well.

BLE and Low Level Development / Re: Simblee BLE Battery Service
« on: November 24, 2016, 01:17:31 PM »
You could use another method around this.
Using SimbleeForMobile, I believe you can simply display the battery status value on the mobile phone.
Using SimbleeBLE, you can use Simblee.sendInt() back to mobile terminal. You might want to try out with Blynk so that you don't need to spend time developing IOS app.

They might possibly release an example next year 2017. But not toward end of this year.

Rohan, Please refer to the RFdigital's demo. You can also send them to the cloud.

Simblee Libraries / Re: SimbleeCOM vs SimbleeGZLL
« on: November 21, 2016, 02:19:14 AM »
SimbleeGZLL based on the Nordic GZLL can only connects up to 8 devices in star topology. (Refer to the link)https://devzone.nordicsemi.com/documentation/nrf51/4.3.0/html/group__gzll__02__user__guide.html

SimbleeCom was said to be connectable to unlimited Simblees. The latency is 3ms.

Not sure about how fast is GZLL.

Both are proprietary standards. Interoperability is perhaps subject to implementation. The industrial standard for connecting multiple devices is the upcoming BLE Mesh.

Hi Patty,
  Pertaining to this one to many topology shown with a phone, is this phone-to-many Simblees or a master Simblee to many Simblees?

Rohan, please refer to this Simblee video at the 4:05 time. https://www.youtube.com/watch?v=FHQObESzrzs&t=276s

You will find that Simblee can connect 100 devices with 3ms latency. Normal BLE will probably connect <8 devices. Using GZLL protocol will also likely be around 8 devices. This is one of the critical point why one would use Simblee compared to the other BLE. It uses the proprietary radio stack of SimbleeCom to do that. It should be able to use BLE and SimbleeCom together. I haven't tried that.

In the video, the phone seems to connect to 100 Simblee. This may possibly feasible with your PC. Is this based on mesh or star topology that I am not sure how it is done in software.

Check out the website from Adafruit on MPR121 setup, driver, schematic etc. https://learn.adafruit.com/adafruit-mpr121-12-key-capacitive-touch-sensor-breakout-tutorial?view=all

Support / Re: Is there HID support for Simblee or RFduino?
« on: November 13, 2016, 07:29:16 PM »
You can find the examples of HID for RFduino by using this library.
Install the BLEPeripheral Library from the Arduino IDE
1. Goto Sketch>Include Library>Library Manager
2. Search for BLEPeripheral and install
3. Goto File>Examples>BLEPeripheral>HID>

There are many HID examples there. The library doesn't work for Simblee yet.

Is Simblee Bluetooth range certified as Class 1 ~100m? Typical design is like Class 2 ~10m. The datasheet mentioned about "long range" without actual data. And the Simblee video shows a customer mentioned about 100 feet (30m) away??

Also, Simblee promotional video shows a 3ms second latency connections to 300 BLE devices? Really??

Support / Re: Simblee - OTA programming?
« on: November 03, 2016, 02:59:39 AM »
I tried using the IOS NRF Toolbox and no Simblee App that connects to the device. I cannot upload the application .hex. It got stuck at Enabling DFU Bootloader....
