    • Tips for troubleshooting and asking questions

      tmonte | 08/217/2019 | 04:14 AM

      1. Clarify to yourself what the specific issue is.

      2. Apply basic troubleshooting:

      • Check hardware connections with multimeter.
      • Use logic analyzers/oscilloscopes.
      • Use Simplicity Studio Debugger/Energy Profiler/Network Analyzer/BG Tool, use logging prints.

      3. Consult the datasheets and reference manuals. Sources include:

      4. Search to see if someone has asked the same question already.

      5. Include the relevant parts of your development setup in the problem description. Examples include:

      • SDK version
      • Part number
      • Radio board vs custom hardware
      • Host OS
      • Mobile phone model and OS version
      • Compiler and compiler version

      6. Include steps to reproduce the problem or specific conditions the problem occurs in.

      7. Be patient and avoid making duplicates of your question.

      Hallo,

       

      I want to add bluetooth communication to my Giant Gecko EFM32 MCU via BGM111 connected via USART and BGLib.

       

      Is there an example how to add bglib communiction into EFM32 MCU firmware?

      Is bglib implementation ready to usage available for EFM32 giant geckco?

    • BGM111 energy saving

      Maddis | 05/134/2016 | 07:52 PM

      I'm doing sensor project based on BGM111 and idea is that I send info out only every minute or so.

       

      I'm using soft-timer to wake up the unit, but I was wondering is there better way to wait that time or how much power does soft-timer consume? 

       

      At the time I have bluetooth adv on to send adv every 100ms. I think I can stop that too and start it only once every minute or so because I have other BGM111 to listen those and react as soon as it hears them. Not sure though how much the adv takes power, but I'm guessing everything counts in long run.

       

      Do I need to enable the sleep mode somehow or does the system automatically go there once it exits the event it was handling?

    • Blue Gecko Simplicity Studio integration

      mapleleafs | 06/167/2016 | 08:52 PM

      I have been holding out awhile now for new updates to Simplicity Studio, and haven't gotten any? What should I expect in the near-term future with regards to BG and Thunderbird react? No demos or Software examples off of Simplicity's home page to date. I am worried about launching in one direction and then getting redirected with an update. Should I just stick with the bgscript that's already out there?

    • Sensor to cloud connectivity

      manordse | 06/172/2016 | 02:41 PM

      This week we introduced the Thunderboard React, a solution made to bring your IoT product ideas to life. The small demo board connects to the free mobile app to get your sensor data to the phone and the cloud. At the center is our BGM111 Bluetooth Smart module, collecting data from motion and environmental sensors. And of course, all the hardware design and software source is available for you to reuse and modify to fit your product.

       

      Head over to the Thunderboard React page to get all the details.

    • Documentation for Thunderboard Sense

      BasilFX | 07/200/2016 | 12:55 PM

      I just received a Thunderboard Sense. Very nifty board with all kinds of sensors and BLE + Thread + ZigBee radio, using the EFR32MG. The board is recognized by Simplicity Studio, but there is no documentation on the internet. Even the schematics in Simplicity Studio itself are for the wrong board.

       

      I am looking for:

       

      • Pinout
      • Schematic
      • Board manual

      Does somebody know where I can find them?

    • Which cloud database do you use

      6thsense | 08/221/2016 | 01:19 AM

      Hi,

      I just wanted to know how users on this forum upload data to cloud. I am considering a use case similar to Fitbit, where data measured by sensors is sync'ed with a smartphone via BLE, and the smartphone uploads the data to the cloud.

       

      I did notice a press release about thunderboard, but am not sure how is can be used with BLE112 and custom app.

    • Thunderboard React Schematics

      ww | 08/241/2016 | 12:29 AM

      Hi - Is it possible to share the PCB design files (Schematics and Gerber) for Thunderboard React? I'd like to use it as reference. I couldn't find them on the Silabs website/community.

       

      Thanks!

    • Thunderboard React firmware

      blueuser | 09/268/2016 | 08:47 PM

      Hi,

      Where can I find the Thunderboard React firmware that works with the phone app to show off the onboard sensors?  I overwrote the original firmware, and wanted to put it back in.  Can I get the binary so I can just load it with EA Commander?  I don't have IAR compiler.

       

      Thanks,

      Eric

    • Thunderboard React firmware is not compiling under Simplicity Studio 4

      IoT | 10/275/2016 | 09:53 AM

      Hello,

       

      Before I do any modification I tried to compile the demo application with no success.

      I installed the new Simplicity Studio 4 under macOS Sierra (10.12) with Bluetooth Smart SDK (2.0.0) and GNU ARM (4.9.3).

      It seams that some files are missing. Could you please advise where these files are located?

      What I already tried to extract these files from Bluetooth Smart SDK (1.0.4.0) under Windows. But with no success, I only got much more errors.

    • Where are the private keys of the Thunderboard React board stored?

      _Alex_ | 10/281/2016 | 07:10 AM

      Hello everybody!

       

      I would like to ask you a question regarding the security features of the Thunderboard React board. It features a BGM111 BLE module which consists of a CRYPTO unit providing support for ECC and AES for instance.

      I am wondering about where the actual private keys of those algorithms are stored?
      Are they saved and protected on hardware or do they have to be hardcoded inside the user program and are stored in flash memory?

       

      Thank you in advance!
      Many Thanks
      Alex

    • BGM111: turn on LED when characteristic written to

      jakes | 10/282/2016 | 08:57 AM

      Hello,

      I'm looking for an example BGM111 that can get me close to doing something like this:

       

      Create a custom service that has a write characteristic.  When a phone connects and write a non-zero value to that characteristic, I'll turn on an output (LED in this case).  After 5 seconds, the BGM111 itself writes zero back to that characteristic.

       

      I'm new to BGScript, so some of the existing examples might be throwing me off track.  Wondering if someone can point me to a more targeted example or set of examples to combine.  I have a Thunderboard React that I'm trying to use this on, so it has an onboard LED.  I'd also like to write the hall effect sensor analog value into a read characteristic.

       

      Thanks,

      Jake
