      THANK YOU Jeff Randall for providing an archive of these documents. I just pulled my RadioBlocks off the shelf (finally have a project for 'em), and discovered Colorado Micro Devices up and disappeared.

    2. Creator Steven M on November 5

      Uh... it's no the same chip. Nevermind.

    3. Creator Steven M on November 5

      @Jeff Randall - Isn't that the same chip these RadioBlocks use?
      I have custom code developed for these chips already... Be nice if I could find another board that uses something similar.

    4. Creator sgllama on October 26, 2014

      @Jeff Randall - thanks for sharing those files (there were a couple I'd missed downloading).

    5. Creator Jeff Randall on October 24, 2014

      I'm going to try using a Digispark Pro along with their nRF24L01 and mesh/wireless shield. I'm currently waiting for Digistump to send me mine from their latest Kickstarter.

    6. Creator Steven M on October 13, 2014

      Wish I had known the company was going to disappear. These things work well and were the cheapest solution for my project I have found. No response from the project creator...

      What have people replaced their RadioBlocks with?

    7. Creator Harry Matthie on September 30, 2014

      #Jeff - - Thanks for the files!!!!

    8. Creator Jeff Randall on August 9, 2014

      @20drig0 P3rez, you're welcome. I think Dave M went missing. I haven't heard from him. I wish Kickstarter had some way of sending PM's to other backers. Oh well... :(

    9. Creator 20drigo Perez [Mx] on August 7, 2014

      @Jeff, thanks for making the files available - I just thought the website was still up.
      @Dave I'm also be interested in getting some more radioblock modules. Write back to parasitoz /aat/ outlook /doot/ com

    10. Creator Jeff Randall on July 24, 2014

      @Dave M, did you send an e-mail? I've been trying to watch for it, but I haven't seen one from you.

    11. Creator Jeff Randall on July 17, 2014

      @Dave M, I'm interested. Can you send me an e-mail to Jeff (at) randallsrus (dot) com to let me know how many you have and what price you're looking for? Thanks.

    12. Creator Dave M. on July 17, 2014

      Anyone want to buy the modules I have? They have barely been used. Since I can't get them anymore, I don't really need to keep them around.

    13. Creator Jeff Randall on June 27, 2014

      You are very welcome! I'm glad I could help.

    14. Creator Martin on June 27, 2014

      Jeff you are a life saver! Thanks. There would be no other way for me to get this up and running without your file posting. Very very appreciated.
      Martin

    15. Creator Harry Matthie on June 13, 2014

      Jeff - can you make the radio block files available. My computer crashed a few months ago :(

    16. Creator Dave M. on June 4, 2014

      I'm wondering the same -- was thinking about ordering more, but now am wondering if I have to find a new wireless solution.

    17. Creator Jeff Randall on May 23, 2014

      Anyone know what deal is with Colorado Micro Devices? Their website is practically blank. I was thinking about buying some more radio blocks. Thank goodness I downloaded all of the documentation and software before they did this.

    18. Creator Leon Woestenberg on March 12, 2013

      Hi Eric,

      all solved, thanks for the hint!

      I checked with the nearest post-office and they had my shipment waiting for me, with customs import tax to be paid. I never saw the failed-to-deliver note.

      Play time!

      Leon.

    19. Creator Eric Gnoske on March 9, 2013

      Hi Leon,

      Have the customs folks contacted you? We have other customers in the Netherlands who have received their packages without issue.

      We'll see if we can find out any other info - If all else fails we will simply send a new shipment but probably using different service.

      Eric

    20. Creator Leon Woestenberg on March 9, 2013

      Hello Eric, thanks for following-up. No, nothing received so far.

    21. Creator Eric Gnoske on March 4, 2013

      Leon - Did you receive yours?

    22. Creator Leon Woestenberg on February 24, 2013

      I did not receive anything yet (Europe), are shipments trackable?

    23. Creator Eric Gnoske on February 20, 2013

      Have a look now - Thought an answer got posted, a response is there now...

    24. Creator jcragris on February 18, 2013

      Hello
      there is no answer on your forum for two weeks?
      Why?
      thank you

      JCR from Switzerland

    25. Creator Eric Gnoske on February 5, 2013

      We're working out the kinks right now. Hope to have it posted within a week. We'll also modify the GUI to use the new library as well...

    26. Creator Rime on February 5, 2013

      Been having fun with the Arduino library, though I didn't see a library for python. Not sure, but is there one yet?

    27. Creator J.p. McGinley on January 31, 2013

      Received my the other day in Virginia. The quick start guide has link for the LPCXpresso kit.
      The link does not work. Newark has a bunck at this link: http://www.newark.com/jsp/search/browse.jsp…
      Is it the LPC1343, LPC1414, LPC1114??? Prices range from 16-33 Thanks for the guidance

    28. Creator Jeremy Southard on January 23, 2013

      Got mine last night, here in Texas! Thanks Eric (and the gang)!

    29. Creator Anna on January 23, 2013

      Already received mine (in Europe) so that is very quick! Testing will have to wait until the weekend, will let you know.

    30. Creator James Hagerman on January 17, 2013

      For anyone trying to get up and running on Arduino, I posted a really hacked together send and receive project using the Colorado Micro Devices Arduino library examples as a starting point. I hope it helps some people get their feet wet more quickly: https://github.com/JamesHagerman/RadioBlock_Arduino_Demo

    31. Creator James Hagerman on January 17, 2013

      Eric, I still have to take another look at what I was doing to cause the behavior I was seeing. I don't have the equipment for firmware debugging but if I can duplicate the behavior I'll post it to the forum on your site.

      I think it may have been me trying to send data too quickly but I don't know how that would have caused the SoftwareSerial port to freeze as well - which it did not too long before the board seemed to freeze. I'll let you know!

    32. Creator Eric Gnoske on January 15, 2013

      We've got a C library (API) that we need to make a few changes to. Runs on an XplainedA1 right now (other folks have it running on a BeagleBone too) - Hope to post the changes very soon. You can have a look at: git://git.assembla.com/simplemesh-api.git to get an idea...

    33. Creator Eric Gnoske on January 15, 2013

      I've started a forum for discussion: http://www.coloradomicrodevices.com/forums/forum/colorado-micro-devices-forum/

      With respect to your comment - How long is "some time"? One of the things we've learned is that the AT86RF231 internal PLL will lose sync after "some time" if it does not change state. For example, if you put it into RX mode and then switch back to TX mode or change to a new channel and then back, that should recalibrate the PLL... See Section 9.7.4 of the AT86RF231 datasheet.

    34. Creator James Hagerman on January 15, 2013

      Oops! I had a typo. The boards DO seem to stop sending out packets after some time. They shouldn't...

    35. Creator James Hagerman on January 15, 2013

      I got my RadioBlocks yesterday and after a lot of trial and error I've come to realize that the firmware they came with seems to be pretty unstable. I've got them plugged in to two Arduinos and my next step is to try and cut the software serial library out of the mix all together. The Arduino code is still running, but the RadioBlock doesn't seem to stop sending out packets after some time.

      Also, when exactly do the red led's on the RadioBlocks blink? On packet send? On packet receive?

      Thanks! I look forward to having more complete libraries and examples!

    36. Creator Tony Guerich on January 14, 2013

      Eric...you have done it again! I just got my RadioBlocks today. Congrats on another successful project. I can't wait to see what you do next.

    37. Creator Eric Gnoske on January 5, 2013

      We switched our web site to a CMS (WordPress) system several weeks back and also engaged a new ISP. We are going to bring up the store soon!

    38. Creator Andrew on December 13, 2012

      When and where will we be able to order more Radioblocks and associated accessories, such as the accelerometer board?

    39. Creator Toby Segaran on December 13, 2012

      Just filled out the survey! I'm really excited to get my Radioblocks, I already have three projects patiently waiting for wireless connectivity.

      Assuming these work for me, how soon until we can order more?

    40. Creator Eric Gnoske on December 12, 2012

      Will post an update tonight and start sending out surveys... First Radio boards are coming off the line now! USB2UART boards are in and we're finishing assembly on the JTAG/ISP adapter boards (header soldering)... Trying hard to start shipping soonest!

    41. Creator spencertc on December 12, 2012

      Still planning on shipping them next week? How is everything going? I can't wait until I can play with my RadioBlock's! Thanks for everything.

    42. Creator Jeremy Southard on November 30, 2012

      Awesome update! Thanks!

    43. Creator Eric Gnoske on November 30, 2012

      Just posted a Manufacturing update! Please check it out!

    44. Creator Jeremy Southard on November 30, 2012

      Hey Eric, I'm very excited to get my hands on some RadioBlocks! How are things going? It's been about a month since we've heard anything and I was just curious if you got the fabs in yet. If so, how do they looks? :

    45. Creator Heri Sim on October 16, 2012

      How many GPIO, PWM, I2C pins is usable?

    46. Creator Evaristo Ramos on October 6, 2012

      wahoo grats!!

    47. Creator Eric Gnoske on October 3, 2012

      Hi Paul - do you want both a ISP cable & JTAG cable, or just wanting to switch it? You should be able to switch the reward I think, or send me a message if you need something more specific.

      @Bob: I can't edit the reward descriptions now that funding has started, so hopefully the update catches peoples attention.

    48. Creator Eric Gnoske on October 3, 2012

      Sorry for the confusion - will update! You still have time to adjust your backing of the project if that's a deal-breaker, we don't want anyone to be disappointed!

    49. Creator Paul R on October 3, 2012

      I have a question about the cable options. I selected a 5 pack option with the the ISP cable. Will I be able to add or order a JTAG cable?
