Tether internet connection directly from smartphone over bluetooth?

[Jon]

Can anybody help me please?

I'm trying to find a chip that will allow me to connect to my smartphone's internet connection over bluetooth.

I don't want to create an app on my smartphone that handles the data connection - I want to connect to the internet directly from the chip itself.

An example of this would be how I can connect to my smartphone from my laptop, over bluetooth and browse the internet using it's cellular connection. 

I've read most of the documentation, SDK and devzone articles and I'm still unsure about if this is possible using any of the Nordic chips :)

I can see examples of IPv6 and 6LoWPAN connecting to routers but I want to simply connect to my smartphone.

Many thanks in advance - I'd really appreciate being pointed in the right direction on this!

Yes, using Bluetooth Low Energy as a "gateway" to connect to the internet is generally a bad idea. But you're of course welcome to try if you'd like (it could work using the 2Mbps PHY available in BLE5 for all I know), in which case the nRF52840 DK would be a good place to start development. We don't have any example code doing something like this though. You'd have to start out with something like our ble_app_template example and work your way up from there. I'd still recommend using Bluetooth classic though, as the 2Mbps mode in BLE effectively has a throughput of  ~1300kbps maximum (that's bits, not bytes).

Best regards,
