Hello first time poster here. I have been working on using the DFU functionality to give OTA updates to my MCU. I believe that I have implemented this successfully however I am wondering if I have something missing. after the success of the update I am not seeing the current version populate in notehub. see below

I am not sure if this is a bug or if I am doing something wrong. any help would be greatly appreciated.

I figure out my issue. It appears reporting the firmware version does not happen in the dfuPoll() function so it must be called in the setup function. i.e.

```auto
req = notecard.newRequest("dfu.status");
if (req != NULL) {
  JAddStringToObject(req, "version", firmwareVersion());
  notecard.sendRequest(req);
}

```
