BLE SIG mesh

[Pavankumar K]

Hi,

We need a BLE chip which can be used as a radio which supports BLE SIG mesh and work on standard HCI commands.

Kindly suggest the right device.

Thanks & Regards,

The nRF52 chips support BLE SIG Mesh at the radio level.

For HCI, see:

If you wanted to stick with the Nordic SDK, you could consider Serialisation:

Hi Awneil,

So just to get clear idea on Hardware side, before finalizing a SoC. 

nRF52832-QFAA is good enough in terms of capability and memory to run SIG MESH on it with HCI ?

Should we go for nRF52832-QFAA or nRF52832 QFAB is also fine ?

I hope i need not use nRF52840 to achieve this one since i  have some cost concerns. 

Do share your inputs.

I've only used the Nordic SDK

As noted above, HCI is not in the Nordic SDK - so I have no idea.

The nRF52832 Dev Kit has a nRF52832-QFAA - and that can certainly run the Nordik BLE Mesh SDK examples...

I would always (not just for Nordic) recommend starting with the higher-memory part; once you have a solid feel for your actual memory requirements, then you will be in a position to evaluate whether a reduced-memory part is feasible ...

We need only BLE without MCU.. kindly advise..

[awneil]

All Nordic's BLE devices are SoC - ie, MCU + Radio.

So, if that's not what you want, then you need to look elsewhere.

But, again, Serialisation allows you to use the SoC as little more than a "dumb" radio - with the "Host" doing most of the work.
