nRF51822 doesn't get detected on Macbook Pro (Mid 2014) OSX 10.10.1

[Chirantan]

We are trying out nRF51822. My colleague has a top of the line Lenovo running Ubuntu and is able to detect the module when scanned. However, my macbook pro Mid 2014 (Which discovers other Bluetooth 4.0 modules) doesn't detect it.

My guess is that my Macbook (or any Macbook for that matter since mine's the latest) is incapable on the hardware side since it can officially only support Bluetooth 4.0.

This might be a very naive question, forgive me for that, but is it possible on the firmware level to switch to Bluetooth 4.0 on the same nRF51822? Or is there no way for this module to be discoverable on Macbooks?

Can you define "detect the module when scanned"?

Reading between the lines, it almost sounds like you're asking:

• "Can my Bluetooth 4.0 Mac not find the Nordic module because it's got a Bluetooth 4.1 stack?". This would be an incorrect assumption.

• But, yes, you can load an older SoftDevice that's only 4.0 compliant on to the nRF51 -- but as I allude to, that's not the problem here.

Give us some more details?

Hey Marc, thanks for a quick response.

By scan, I mean bluetooth scan for devices. My Mac is Bluetooth 4.0 and the nRF51822 is probably running a 4.1 stack (I don't know how to find out for sure). I guess your bullet point two is possibly the answer. But then the question would be how do I load an older SoftDevice?

Are you using one of our development kits? Or a module? What version of SoftDevice are you using? What SDK version? How are you detecting the device? Can you try to sniff what is happening on the air? Please edit your question and include some more information.
