In other words, in terms of Bluetooth qualification both the GAP profiles appear to be separate, but on the device itself it is one GAP profile. What I mean by this is that if you have a Classic-only device, then the qualification will be against the classic GAP profile, while if you have and LE-only device, then the qualification will be against an LE-only GAP profile. However, a device can support either one or both. No, the same GAP profile is applicable to both classic and BLE. Yes, both EIR and AD elements are defined by the GAP profile. device name) from EIR data and AD data be different ? Is Gatt Server running before connection is formed ? If not, then how is GAP profile (used for advertising) relevant before connection ?Ĭan same fields (e.g. When we enable advertising (low energy) using hcitool cmd or enable discoverable mode (classic Bluetooth), how does controller get all the advertisement information (scan response/ extended inquiry response)? Is it stored on controller?Īs mentioned in Bluetooth Specification 4.2 section 7.8.8 LE Set Scan Response Data command can be used to provide data for scanning packets. Is there a different GAP profile for classic and different GAP profile for LE ? Where is data from GAP profile stored? Is it on host or controller? Is EIR data (classic Bluetooth extended inquiry response) and AD data (Bluetooth low energy scan response) read from GAP profile. I have few queries regarding the scanning and advertising of classic and low energy Bluetooth. Then sit back and watch the magazines drop onto your doormat through 2010.I was trying to understand basics of Bluetooth.
So if you’ve been thinking about subscribing to Stack, or if you know somebody else who’s mulling it over, make sure you (or they) sign up before 1 November to avoid paying the higher prices. And of course in many cities around the world it’s just not possible to buy one-off issues of the magazines available on Stack. Overseas subscriptions will cost more per issue to cover the increased cost of sending magazines by airmail, but even with the higher prices it will often still be cheaper to buy from Stack than to buy the same magazines off the shelf overseas.

A full list of subscription prices is included below. I wanted to keep the subscription price below that, so from 1 November anyone buying a UK subscription to Stack will pay £4 or a bit less per issue. So what will it cost? The average price of the magazines I’ve sent out so far is £4.68 – that’s what it would have cost, on average, if you’d bought them off the shelf in any shop in the UK. It’s still going to be brilliant value, but it will also be sustainable enough for me to carry on sourcing and sending out the world’s best independent magazines into next year and beyond. Stack isn’t in dire straits but it will be if I don’t do something about its finances, so I’m going to raise the subscription price from 1 November.

When I started out the business plan looked great, but then Royal Mail put up its postage prices at the start of April, and a series of other unanticipated costs have rolled in. Which brings me neatly onto the main thing that needs to change about Stack. There’s no money here for advertising so Stack really depends on word of mouth to keep on growing. It’s also fantastic to have so many subscribers who take the time to let me know they’re enjoying the service, and who recommend Stack to friends. I had no way of knowing at the start that so many publishers would throw their weight behind the idea, and I’m incredibly grateful to them all for their support and advice, and of course their magazines. The things I’m most pleased about are the quality of the magazines I’ve been able to send and the enthusiasm of the community that’s building around Stack. It’s a year now since I first started working on the idea that turned into Stack, and looking back there are some bits I’m very pleased with and some bits that need to change.
