ISD Go

App starts, connects to esc, but connection for firmware update was so unstable, that i thought i bricked the device. It succeeded on the 4th try…

It is finding the device (isdt70A) but can't connect to change the settings.

What ever you do don’t update the software because you will never connect to the discharger again through Bluetooth. These developers don’t even care to fix the issue. So don’t buy the ISDT FD-200 if your looking for the Bluetooth features.

Doesn't stay connected via BT, more Error messages than anything, not terribly intuitive, timeout messages etc, just a lousy non functioning app all around.

Yes, you read that correct. I tried many devices a year ago to get this stupid device to work. Mine came titled as brand new but someone had opened previously. After this method I am having no disconnecting issues. It was simply an error on the devs programming. I tried my iPhone, SamsungS8 & S2, iPad 11”. Then recently after a year past my OG purchase I tried it on my iPad Pro 3rd gen 12.9 running iOS13.3

I just got the FD-200 and the app will sometimes connect and let you make changes but it always disconnects while discharging. Doesn’t matter where my phone is, next to it on either side, on top, in front or behind it still disconnects.

Using it with an FD200 discharger. The app is useless it disconnects from discharger or does not connect. Also when lucky enough to get it to work the unit keeps discharging batteries regardless of parameters selected on the app. Renders the FD200 useless as it will continue discharging lipo batteries below the point of no return. Shame as it was a functional product before the latest update.

Most I am able to do with the app and FD-200 on my iPhone is select my parameters and start the discharge process. Shortly after it disconnects and won’t connect again for the whole process. The discharge process on the FD-200 completes as it should for what it was initially configured. So long as you set end voltage and current, the cycle will automatically end there not draining your packs excessively. This has been an issue for over a year now, that I have seen absolutely no improvements made for it whatsoever. I brought it to the attention of some of the folks at Isdt but they must not have thought it was important. I sincerely hope to see this get fixed soon getting the attention it deserves.

I have 2 ISDT FD-200 dischargers which I’ve tried to connect to via Bluetooth however they disconnect after a few seconds of being connected or when you try to update the settings.

Please fix the glitch from the last update that disconnects the Bluetooth after a few minutes of discharging every single time rendering the app pretty much useless.
