I have a project that needs a Chinese short-range transceiver that I=20 have located a cute, cheap module for, with built-in antenna and all.. The BK2421 is supposed to be easier to use than almost any other=20 transceiver. Its popular there, so I've heard (check is in the mail, etc) I have the datasheet, which looks easy all right. I have been burned=20 before, though. Anybody playing with it yet? --Bob 520- 792-8344 fax --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
