Support / Simblee GZLL performs worse than RFduino GZLL?
« on: March 18, 2017, 06:18:24 AM »

Previously I had excellent results with GZLL on RFduino modules, typically sending 2 to 4 byte packets each 8.3 ms.

This year I made a new system using Simblee and found some gaps in my data.  There are periodically chunks of 5 or 6 data packets in a row (approximately 60ms lost time) that do not arrive and thus do not receive an ack.  I have a packet counter and check the ack against this counter.

I have the same code, switchable between RFduino and Simblee modules with #define statements.  On the RFduino the communication is very reliable unless I push the packet rate to each 3ms, and even then I just lose the occasional single packet.

NOTE: I have tested this with Simblee dev boards as the transmitter and receiver.  I did this to confirm that my hardware was not the root cause.  Also, I am not using any Bluetooth or Simblee for Mobile.


1. What can be happening to interrupt transmission of GZLL packets?  difficult question of course!

2. Can the Simblee modules be programmed with an image that would convert them to be RFduino?  That would be preferred if the root cause of this difference is the library.

3. I tried to compile a new GZLL library using the batch file in the sources but it fails because many files required by the batch program are missing.  Could these be made available?

4. What are the differences between GZLL on Simblee and GZLL on RFduino?  Maybe I can adjust the registers to accommodate the difference.

5. Is Simblee still an active project or is it cancelled or abandoned?

Thanks in advance for any help or advice!


Simblee Libraries / SimbleeCOM vs SimbleeGZLL

I have used Gazell on RFduino in a couple of applications - internal test tools in my company.  I understand that Gazell is a Nordic product but I don't know what SimbleeCOM is.

For a new project I have two tools that will send data to a 3rd tool and I am using Simblee modules.

What are the differences between SimbleeCOM and SimbleeGZLL  - how would I choose?

I do not need BLE but I may choose to add it later to improve usability of the design.

Getting Started / pinout reference

Is there a guide to explain the different uses for the gpio pins?

I have searched but google has not indexed very much stuff yet.

Is there a hardware reference somewhere for this -open source - project?

I wish to connect an I2C device and communicate with the wire library.

I am following the quick-start guide.  Downloaded and installed Arduino 1.5.3 on Windows 7.  The USB driver installed and is a new port, COM12 that I can select from the menu.  I have restarted the computer.

 - RFduino does not show up in the Tools menu under boards

 - What should I expect for LED activity on the rfduino and the USB board?

 - Would RFduino show up in the menu even if RFduino is not running for some reason?  would it show up even if I disconnect the USB shield from the computer?
