Suggestion on updated IC (BLE+MCU)

[Sujai]

Hello,

We require a bluetooth low energy IC with MCU. Right now we are testing with nrf51422 development board. Could you please suggest any updated ICs with (BLE+MCU) ?

Hi Sujai!

For an updated MCU with BLE, I would suggest the nRF52832. It has support for Bluetooth 5, more flash and more RAM.  However all our SoC's are what you describe as BLE + MCU.

If you could describe a little more in detail what you are looking for, I could perhaps assist you in selecting the best one for your application.

Best regards,

Heidi

Thanks for the reply.

Let me give you some more details on our application. I wanted to develop a bluetooth dongle where it will communicate with multiple devices (3 to 4 bluetooth enabled devices) simultaneously (both read and write operation) at 5ms without any data loss. As I told you right now I have nrf51422 dk board and IC. Is it possible to do the same with this IC?

Hi,

7.5 ms is the lowest possible connection interval, so 5 ms is not possible.

Have you considered using the nRF52840 Dongle for your application instead of using the nRF51422 and an external USB chip?
