ask module
i have a problem on the receiver, its has a output with-out any input..''and pls upload application note for this..
thank you
i guess this is the site
http://spiriton.manufacturer.globals...-RF-Module.htm
anyway..dont have a reply :( if i have an output of 9800 or 4600 baudrate, can you suggest a filter circuit? because its to noisy!
that is naturally noisy because it operates on unlicensed frequency band which is similar to a crowded room, difficult to communicate, you have to add error detection routine to communicate successfully, i used similar module http://www.youtube.com/watch?v=yhoq1hGIG1Y
could you share you experience on that module? any possible or suggestion for a design on the receiver part?(e.g antenna length, PCB routing)
Added after 7 minutes:
i guess what you did is filtering the data by means of software..right?
PCB routing and antenna length are not critical in its operation, most processing of proper data acquisition is done by software
Thanks..thats all i need
another thing...do have some specs on it?
very similar to that in your posted link only differ in brand
i just found that on net..but i dont have the datasheet...can you share what you have?
this is the brand sold here in asia
