MICROCHIP - RN-42-SM - EVAL BRD, BLUETOOTH CLASS 1/2, SOCKET MODULE 2 5 1 1
Roving Networks needs to be more accurate. *HID* In the linked data sheet it says this device supports HID. Well It does, but it doesn't. The device is shipped with a firmware 4.77 (latest stable SPP firmware). This firmware doesn't support HID. That's fine, so I go look for a firmware update. I find this, " There is currently no way to upgrade Bluetooth firmware in the field. Please contact your local sales office." You have to special order the one with the HID firmware. Or look for the old releases that don't quite work perfectly. Those models are, RN42HID-I/RM603, RN42HID-I/RM610, or RN42HID-I/RM611 (this is their latest "stable" HID release as of 1/2012). As for the device itself. It's well built and SPP works great. NOTE: If you plan to use the UART interface, you have to unsolder Resistor R6 and R8 for it to work or you get garbage characters in the terminal. I understand the reason why, but they should have made 2 jumpers for that instead. Since, after prototyping with UART, I can't try the other method. The status LED's are very helpful as well. In UART mode it has voltage regulators so you can use 5volts and it will bring it down to 3v. Which is a nice touch in prototyping. (Those Arduino people will find this useful) I really like this chip reconnection method, but if we can't update these ourselves we have to find another solution. January 9, 2013
