Migration from BlueNRG-2 to BlueNRG-LP

[_KSoni.3]

Hello All,

I am working on a custom board which has BlueNRG-2 IC as a connectivity chip with Mobile App. I am now planning to migrate to BlueNRG-LP IC because of memory limitation in BlueNRG-2.

Is there any migration document for the same?

Following are the components which I am currently using in BlueNRG-2:

• UART
• DMA
• SPI
• Bluetooth
• JTAG

Hi @_KSoni.3​ ,

There is two aspect to consider while migrating from BlueNRG-2 to BlueNRG-LP :

• Peripherals as you mentioned
• BLE stack APIs.

At first, let me say that code philosophy is the same between BlueNRg-2 and BlueNRG-LP. That means that if you are used with BlueNRG-2, BlueNRG-LP will not be a proble.

To start, I would advise to download and install BlueNRG-LP SDK. It includes multiples code examples and some of them should already answers your needs - In my opinion, probably easier to modify those code examples for your own needs. There is also dedicated code examples for each peripherals ( UART/DMA/I2C/SP/...).

Coming back to migration ( BLE stack migration), either you can use code example from BlueNRG-LP SDK or it exists a Migration BLE stack guidelines from v2.x to v3.x.

In any case, whatever your approach, you should consider a code example from BlueNRg-LP SDK as basis for your development (this is easiest way in my opinion)

This doc is part of BlueNRG-LP SDK : C:\Users\USER_NAME\BlueNRG-LP DK 1.1.0/doc/index.html
