Hi

For a new project I'm looking for a cheap bluetooth chip.
All my software resides in a PIC, because on PIC I have a lot of experience and I don't have the time to dedicate myself to learning new development systems.

The need is to send and receive data packets, "NO AUDIO", sending said data preferably with i2c system, alternatively with spi system to the chip which will simply serve as a radio rx - tx fullduplex

Thanks

Hi 

It's a bit difficult to be sure if the modules you linked are genuine or not. The fact that they are very cheap, and don't mention Nordic Semiconductor anywhere in the product description, means there is a high risk they could be fake. 

I would recommend buying a couple of known good modules from a site such as Sparkfun:
https://www.sparkfun.com/products/691

Once you have these known genuine modules running you can try the ones you already have, and if they seem to work the same way you can keep using them for development and testing.

1) We sell all our parts through distributors. 

Integrating the chip on your PCB reduced per unit BOM, but increases development complexity and time to do the PCB design. You also need to spend some money to get your PCB RF tested to comply with local regulations. 

2) You can find an overview of our distributors in Italy here:
https://www.nordicsemi.com/About%20us/FindDistributor/Europe/Italy

3) As mentioned I would recommend one of the Sparkfun modules. I am pretty sure they ship to any country in Europe. 

www.mouser.com also seem to have some nRF24L01+ modules available. 

4) We did make a devkit for the nRF24L01+ back in the day, but it is very old and not well supported anymore. I think it will be easier for you to get a module and hook it up to your PIC devkit instead. 

Best regards
