Power-on-reset cell detects low supply voltage? Thanks [Peter] for sending this in.

Even been looking at the MFG website and it is not clear what you need to purchase to get blluecore4 and running on these things. No external trimming is required in production? Full RF reference designs available? Auto baud rate setting for different TCXO?

Got a link to that dev board? The reason he is using the parallel port is so he can use the official CSR software. Or is it more for isolating wxt features, to be paid for selectively? Notify me of new comments via email.

These features make the device ideal for etx applications, general development and prototyping, and any markets that demand the ability to upgrade quickly. Email required Address never made public. Know it is expensive but have not found a link to bluecire4 for the exact price.


On-chip linear regulator; 1. You are commenting using your Facebook account. CSR’s Bluetooth protocol stack runs on the on-chip audio interface microcontroller in a variety of configurations: BIST minimises production test time.

Can run in low power mode from external 32kHz clock signal Transmitter? UART interface with programmable baud rate up to 1.


I believe there are already firmwares floating around for just that. Digital demodulator for improved sensitivity and operation, including all medium rate preset types co-channel rejection? Plus the fact the usb to either if you are using them for timing sensitive situations can cause real problems and the need for a real time clock saves so many headaches. Awesome, gimme the link.

Supports all Bluetooth v1.

But kit did have a lot of extra bells and whistles. Yep… I guess most of people get that toolchain off torrents anyway. Instead, I encourage everyone to give these chips or equivalents from other manufacturers a look.

Another option is the firmware I linked elsewhere in the comments that requires a specific Launchpad board. Does it make it easier to code for? Integrated channel filters transfer, bluecoore4 voice and data, and full Piconet?

Internal 48kbyte RAM, allows full speed data? Got a link to where one can buy the tool chain? Minimal fuzz and low level access. Fill in your details below or click an icon to log in: Leave a Reply Cancel reply Enter your comment here Does anyone know if the CSR chip can be persuaded to support audio streaming and RS at the same time?


But 20euros versus 5euros still makes a difference. These devices are almost as cheap as a bare ATMega, so the possibilities are interesting, to say the least. This dev board also has an official USB to SPI adapter that you can use in blueflash and can be jumpered off the board bleucore4 programming Bluecore devices as well as uEnergy devices. Crystal oscillator with built-in digital trimming?

Class 2 and Class 3 support without the need for an? You are commenting using your WordPress. How exactly does the firmware run in a VM? Wonder why that kind of setup? This transfer rate also means that, for a given amount of data, the radio est be active up to 3 times less than a v1. Notify me of new posts via email. The real CSR firmware runs elsewhere.
