I am in the process of converting a circuit from using a 433.92MHz radio receiver to using Bluetooth. I bought one of those cheap modules (http://www.ebay.com.au/itm/ws/eBayISAPI.dll?ViewItem&item=270962306229)
I have managed to get it working and receiving data from a PC that is running Tera Term. One problem I have is that whenever I drop power to the module, for example every time I download a new program, it loses pairing and does not reconnect. I have to Remove Device then Add Device again in Windows for it to reconnect, which takes about a minute.
I spoke to the eBay supplier and he replied that he has the same problem with Windows. I am only using Windows for testing. Have others had the same problem?
The purpose of the exercise is to be able to send data to the module using an app on an Android phone, possibly something like Bluetooth File Transfer (http://www.medieval.it/blueftp-android/menu-id-68.html) or Mintoris Basic (http://www.mintoris.com/)
Does anyone have experience with transfering data from a phone to one of these modules please? I don't even own a smartphone at this stage (I still just use a phone as a phone) and don't want to buy one if it is not going to be able to do what I want.
