Looks like Zigbee has gone the route of USB in requiring membership to use their technology: http://www.elecdesign.com/Articles/Index.cfm?ArticleID=13412 "e. Developers incorporating the module into an end product ZigBee: This type of entity must be a member, as either an Adopter or Participant. They must also obtain ZigBee product certification if they wish to use the logo on their product. Product testing is defined and straight forward. If they are an adopter member, there would be an additional $1,000 logo admin fee for the first product ($500 thereafter). There is no logo fee for Participant members. f. Developers incorporating a self-contained ZigBee product within a product ZigBee: If it is contained within the product then this case is treated the same as e). If it is already a ZigBee Certified Product and can be separately packaged as an accessory and plugged in to a PCI slot, USB port or other I/O by the end user, then no membership or additional testing is required." -----Original Message----- >From: Steve Baldwin >Sent: Sep 20, 2006 3:43 PM >To: "Microcontroller discussion list - Public." >Subject: Re: [EE]: Bluetooth to RS232 converters -- source, schematics? > >On 20 Sep 2006 at 0:59, Vitaliy wrote: > >> So in your opinion, if you're dealing with 1k+ quantities, is it less >> expensive to buy rather than manufacture?
