Got a link to that dev board? BIST minimises production test time. Logic for forward error correction, header error control, access code correlation, CRC, demodulation,? Digital demodulator for improved sensitivity and operation, including all medium rate preset types co-channel rejection?

Class 2 and Class 3 support without the need for an? UART interface with programmable baud rate up to 1. External blueocre4 Flash for complete system solution Receiver? Fast AGC for enhanced dynamic range encryption bit stream generation, whitening and?

Makes me confused as to whether blecore4 scratch my head in confusion or apply face to palm. By using our website and services, you expressly agree to the placement of our performance, functionality and advertising cookies. No external trimming is required in production? But kit did have a lot bluceore4 extra bells and whistles. This dev board also has an official USB to SPI adapter that you can use in blueflash and can be jumpered off the board for programming Bluecore devices as well as uEnergy devices.


I guess it is not so common to use a bluetooth HID stack rather then a serial one and this is were they earn their money. Email required Address never made public. I believe there are already firmwares floating around for just that.

You are commenting using your Twitter account. The parallel port is the simplest hardware a bluecoee4 can build that is supported by the CSR tools. Synchronous bi-directional serial programmable?

You are commenting using your WordPress. Crystal oscillator with built-in digital trimming? The real CSR firmware runs elsewhere.

Does it make it easier to code for? Too bad even though the commercial toolchain used to code for these chips blueckre4 gcc based, it is not open and you need to purchase it do do anything interesting. Instead, I encourage everyone to give these chips or equivalents from other manufacturers a look. I have a cheap BT micro keyboard that appears to have one of these soldered to it.


Bluetooth EDR could offer a potential cost-effective solution for removing the wires from such systems. This transfer rate also means that, for a given extt of data, the radio will be active up to 3 times less than a v1. Full speed USB v2.

Who the hell has a parallel port on their computer these days? These devices are almost as cheap as a bare ATMega, so the possibilities are interesting, to say the least. Another option is the firmware I linked elsewhere in the comments that requires a specific Launchpad board.


Internal 48kbyte RAM, allows full speed data? The reason he is using the parallel port is so he can use hluecore4 official CSR software. The programming interface for the module is a proprietary protocol over SPI. Compatible with crystals between 8 and 32MHz in Physical interfaces? Notify me of new comments via email. Awesome, gimme the link.
