maybe you should first explain what you want to do. Why do you want to change the frequency manually? Bluetooth is based on frequency-hopping with 1600 hops per second on 80 different frequencys and the hopping-sequence will be calculated in the lower layers of the bluetooth-stack based on the BT-Address of the Piconet-Master, so it makes no sense in my eyes.
But it is possible to send and receive on single frequencys (implemented for RF-Test and certification) with special HCI-commands.
I have inquireed the price of the module and the chip, for $40 and $10 respectively.
But I have to buy its kit and soft which are more esspensive, $3000.
So, if I only buy the chip, can I use it without many problem of how to control it ?
Or in another word, can I just contol it with a 89C51 ?
BlueCore01 is Prototype your Bluetooth equipped product.
BlueCore01M is Optimise your Bluetooth equipped Product.
BlueCore02 is 1chip solution for mass market Bluetooth product.
BlueCore03 & BlueCore04 is Ture stand alone solution.
Itegrated Bluetooth protocol fast route to market.
Yes, I have the reference designs, maybe i will DL it next week. Don't think about to build the module by yourself, because:
1. CSR-Bluecore is an BGA
2. you have to add at least a 4M-Flash (also BGA)
3. the PCB is a 6-Layer-Design
But if you really want to do it, i can send you the whole stuff( Schematics, gerber...)
Hi drdevcon ,
I will realy appreciate it if U UL (not DL) it.
12The CSR is BGA, why the flash is BGA too, can I change it with lead package ?
3I would rather make a double side PCB board than 6-layer, even it will be larger than before.
And I will be helped by my teachers and my classmates.
So,I have decided to do it, PLZ send it to my E-mail: firstname.lastname@example.org (25M) and email@example.com (5M) .
Thank U very much.
I UL some data about CSR based Modules to FM1/drdevcon/bc01modules.
Also included are schematics and Gerber-data for different modules and some datasheets
Bluel@b2.0 is alredy in FM1/drdevcon/blab
next i will UL Bluesuite to FM1/drdevcon/bsuite
I would suggest you to buy a CSR module that is compatible with OpenBT, and forget about the expensive development kits such as Casira, it is a dumb version of the module bundled with some bulky but not so useful accessories. In case you can get the firmware upgrade from elektroda, the Casira is really meaningless.
Either BlueZ and OpenBT are running on Linux with full source code available, so you may start with tweaking them.
Thank U for Ur message.
I am not very familar with the Bluetooth.
So I donot know what the Casira is.
I only want to design a module by myself to replace the CSR one , which is much more expensive than the chip BC01b-USB.
Can U suggest more ?
I have DL all the files,
but I donot know how to use them actly.
Would U plz tell me the usage of them in detail ?

at first: U can only use the soft if you own a CSR-Base BT-Module.
But the U can:
With Pstools (Bluesuite): read and write internal settings of the module
With Blueflash (Bluesuite): change firmware of the module
With Bluetest (Bluesuite): make some measurements and tests of BT-Connections (like BER, Fieldstrength and so on)
With Bluelab U can develop small Applications ( like Headset-Profile) running onchip in the CSR-Module.
And maybe you should also read this:
Ebook: *B*l*u*e*t*o*o*t*h* Application Developer’s Guide **broken link removed**
I am in a student group working for Bluetooth. All of them R working for protocol, and I must prepare the hardware of it. So I have to design the RF module but not the chip , for the chip's cost will much more expensive than module.
Can U give me some suggestions ?
my E-mail: firstname.lastname@example.org
thank U again.
