@Janek , I have taken part numbers from mouser as reference. I am dealing with my local vendor only. But the local vendor gets product from some other vendor like mouser so it takes so much time and i need to explain them exactly to get things. And thanks for the info.

Though keep in mind that until recently (no idea if it's changed) Mouser was still shipping the G0 version of NRF51822 which isn't guaranteed to work with the recent soft devices. Perhaps it's safer to deal directly with a local distributor for Nordic.

I don't know the legal issues in India but hopefully you could apply for a partial refund at the post office. As for the antenna, any 50 Ohm 2.4Ghz SMA antenna should work. You can search through eBay for really cheap ones.

For chip samples, take the QFAA for development (256kB of ROM, QFAB has 128kB of ROM for less complex applications). You are ordering only a few of them so it really does not matter if you buy R7, R or T. R7 means 7'' reel, R is 13'' reel, T is tray. This is important for manufacturers to order a correct packaging option which can be used in their pick&place machines.

Best, Marek.
