I2C pins used in ISP130301

[jpaetau]

I plan on using the ISP130301 and would like to ask the following:

1. I would like to start my schematic and layout using the ISP130310 from Insight Sip and would like to know the preferred I2C pins for a given firmware load.
2. Ideally I would like to receive from Nordic a firmware load (XYZ) that you recommend for the BLE sip so I could do my layout and schematic accordingly, and preferrably order this parts and recommended firmware to avoid any risk. I understand that the I2C pins can go on any GPIO but at this stage we just want to try it and have it work. Later we may need to modify the BLE firmware..but not now
3. Could we get the ISP13301 preprogrammed with your firmware so we just populate the boards?
4. Are there any other external components necessary to the ISP130301 I need to add to my schematic?

thanks for your help

Bay6Sense is a new startup with connections in the Bay Area California developing Consumer wearables and Power management systems. this BLE device will go on both of these projects.

This doesn't make any sense. Looking at the datasheet for the ISP130301 nothing is "connected to two sensor chips", nothing is connected to anything, the GPIOs are all available for you to choose and connect as you wish. So if something is connected to two sensor chips that means you already have a schematic and you've already chosen and connected two GPIOs so you can do that for two more.

The only firmware (XYZ) which Nordic provides is the bluetooth softdevice. That doesn't deal with GPIO connections or peripheral usage at all. That's all code you need to write.

Perhaps you'd be better off buying an nRF51 development kit, breadboarding your peripherals and developing the firmware, then you design the board.

And the nRF52 series has (limited) NFC capabilities built-in, so if you only need a simple NFC peripheral, you might be better off with that chip.
