Q: airdrop problem between macbook pro 2015 and iPad air

I bought a mac book pro with retina in June 2015. I also have iPad air an iPhone 6 plus. After updating the last ones so iOS 9 its impossible to send data from macbook pro to both devices. I have also installed el capitan on mac book pro, but it even doesn't work. Settings are ok. Data transfer between mac book pro before updating do iOS 9 worked perfectly. Data transfer between iPhone and iPad is no problem as ever. Can one of you help me? Thanks,
