When first received, they both did connect to the BlueNRG GUI app, but with more tests, they no longer will connect - they show up as not detected. However, both boards connect and program OK with the BlueNRG-2 Navigator v 3.2.2 application. Both boards mount as hard drives on Microsoft File manager: One as IDB008VX (with a BlueNRG-2.htm file) the other shows up as BLUENRG-1 (with a BlueNRG-1.htm file)
What do I need to do to reprogram them back to original state so that they will connect to BlueNRG GUI app? I set the baud rate to 115200 baud and use the FW stack version: BlueNrg-2 Fw v2.x The 2 devices show up on the Port: window pulldown. But when I select and open the port, I get the No Device Detected popup.
When this first popup is closed, I get a 2nd popup:: No Firmware detected on the motherboard.
I update motherboard Firmware (under the Tools menu). I do this (Flash Motherboard firmware) but it fails also. Which Firmware should I select? HW and FW versions are not valid, but the Motherboard FW shows up as v1.6.
Is there a document that shows step by step instructions on how to recover these demo boards for use with the BlueNRG GUI app?
