Hi,
I have started a process to develop an Arduino based nRF51822 project.
One of the keystones is that all parts that is developed in the project is under GPL and is will comply fully with "Open Hardware" and "Open Source" licenses.
In the case where "Binary blobs" with licenses that doesn't comply with GPL exists will a wrapper be developed in the same way that the Linux kernel does with some firmware.
Volunteers is welcome to contact me.
The goal is to be an open source alternative to other similar devices.
More projects is in development but is to early to be disclosed (Sorry Christmas is coming to fast).
Kind regards
Mats

Hi There I did not back the RFDuino project but have placed a Pre order which has Yet to be charged/delivered. I think its a very well engineered product at a good price. Time will tell how their current strategy will pay off in terms of growth of their product. With that said competition is always a good thing so here is my personal wishlist for consideration in developement of competing products. * More IO * PCB designed to fit for example - www.hammondmfg.com/pdf/1551N.pdf for a professional looking end result * OTA programming - This does seem possible with the NRF51822 chip I dont know however if a third party designer will have access to the tech. * On board power source (CR2302) and vreg for external supply - does not require additional board to power the device * Interface pins standard 2.54mm pitch so that board can be used in veroboard/breadboard for prototyping. * Interface pins unpopulated with headers supplied seperately. * Some basic sensors like temp and accelerometer on main board. * RGB led on main board. * Daughter boards with advanced sensors or comms interfaces like RS232, RS488, Etherenet and WIF bridges My biggest problem with existing products currently on the market is that most end users will be stuck with the apps that the supplier provides. Most are not interested in taking the time and acquiring the resources to do app developement on their devices. A very interesting alternative I saw recently on a Indiegogo project is that the UI is built by code from the devices side. If these guys tech can be made to work with other creators HW I would be happy to buy their app - www.annikken.com/andee/ |

Hi Mats... I've briefly looked at the documents on the nRF51 series, and the SoftDevice specs... ..still have lots more to read and digest...the holidays will slow that down..  Couple of initial questions occur to me.. 1) Which version of the SoftDevice is in our RFduino chipset? It was not clear to me how to verify that.. 2) Can the current version be upgraded, if desired.. -regards, -=chane |

hi drobscure, you would loose the certification if you change the BLE stack. Either you go with actual Nordic stack, or you enjoy the (soon full certified) RFduino stack which will not be updated so frequently. Think about it. hi iwalker, you can order the RFduino equipment at this onlineshop, where it´s stocked and available: www.rutronik.com/RFduinoor you search in the shop www.rutronik24.com with the keyword RFD90102 for example. It works and I´ve had my RFduino within 2 days. |

Hi GermanStarter...
As a note of clarification.. I do not want to write or modify the internal BLE stack on the chip.. however, I do want the option of changing out the stack for more current versions as they become available...
Mostly though, i want access to the functionality of the stack through the SDK, etc.. without the limitations of a third party 'thin layer' that obscures the available functions of the stack..
If you have knowledge on how to do that, I would be very interested..

I don't think this is open source but it is worth a look for ideas, it has what I would have liked, remote loading of application. launch.punchthrough.com/ |

well I know some guys who started with CC2450 and all of them stopped and switched to nRF51 or modules based on this chip from Fujitsu or RFdigital... all of them claimed the same: support, bugs, current consumption.... looking forward to read your experience later on. world is moving of course...
