bluetooth mesh for newbies

Stas

I'm very newbie in bluetooth mesh. So the question is ..

1.Can I execute any of peripheral abilities (I mean spi, twi, adc, pwm and etc) on device that works like a node in bluetooth mesh or it has to be very simple application?

2. Should I consider bluetooth mesh like other totally different type of bluetooth device communication (with different rules and conditions) compare with BLE?

    Hello,

    1. Yes. You can definitely use the peripherals on the nRF at the same time that you use mesh. 

    2. Bluetooth Mesh is a different protocol than bluetooth, so this means that BLE devices can't automatically connect to a Bluetooth mesh network. The Mesh network has a protocol that is built on BLE advertisement packets, so you can use the nRF52 series for both BLE and Mesh, also simultaneously (multiprotocol). There are a couple of examples in the Mesh SDK that does this already. They typically use BLE for provisioning, where it receives the network keys through a BLE link to a phone. Of course, you can configure the application to do other things with the BLE link as well.

    It is worth mentioning that a Mesh network will have a lower payload throughput than what is possible in a "normal" BLE link. The devices in a Mesh network doesn't have connection intervals like the BLE link, so the radio is by default always on, listening for packs from within the network.

    Best regards,
