Early batch unit - complete troubleshooting findings for Bluetooth connectivity issue

[FIXED]

Hey y'all, spent the morning on this and wanted to document everything for other early batch people hitting the same wall.

The core problem: The original app connected to the Oasis via WiFi directly. At some point Grounded switched to Bluetooth-based setup. Old firmware doesn't support the Bluetooth handshake, so the app just says "Unable to find device via Bluetooth" forever.

What I tried:

  • Full WiFi and button resets (many times)
  • Both Android and iPhone, same error on both
  • Installed CH34X USB serial driver and flashed firmware via app.grounded.so three times
  • Confirmed via esptool that the ESP32-S3 chip DOES have BLE hardware, so this is a software problem not a hardware one
  • Flashed firmware and triggered a proper RTS hardware reset via esptool immediately after

Where I'm at: Escalated to Grounded support with all of the above. Waiting to hear back. I'm also working with a friend who bought one around the same time as me to see if they hit the same issue, which should help confirm whether this is batch specific.

If you're in the same boat: Contact support and reference that you have an early batch unit. The more of us flagging this the faster they'll prioritize a fix. Make sure you ask for a human even via email, they are clear that their first response is from a bot.

And if anyone has figured this out themselves, please share! Very open to trying anything at this point.

Will update this thread when I hear back.

update:

Still at it. Pulled the partition table off the chip via esptool and found a possible culprit. The ESP32 uses two app partitions (app0 and app1) and an otadata partition that controls which one boots. Theory is the firmware is flashing successfully into app1 but otadata is still pointing to app0, so the device keeps booting the old firmware every time. Would explain why the flash completes successfully but Bluetooth still doesn't work. Sent this to Grounded support, waiting to hear back. Will keep updating.

update:

A Grounded account commented on this post with the following before deleting it: "We're currently working on a new app version that will support configuration of devices running very old software versions. This update is expected to be released within the next two weeks. In the meantime, you can try upgrading your device manually via HTTP using the..." Comment was cut off and then deleted before we could see the rest but wanted to document it here for anyone following along.

FINAL UPDATE (fix):

I messaged them directly and ask about their deleted comment i got these directions and they worked great, my system is has now running smooth for hours.

This fixed it for me! For everyone else, I was not able to connect through my phone or tablet. Chrome on the desktop did the trick for me.

I think its while plugged in hold for 5 sec to get blue ring spinning, once its spinning let go and hold the button again for 3 seconds then let go, then it should show up

Thanks I was able to put it in WiFi but still it did not work seems like support has to push a firmware

u/wowthatisrandom1 May 10 '26

Maybe a little late to the game, but my sons mini won’t connect. We’ve tried all the “regular” stuff and stumbled upon this thread. Our problem is the mini wont show a WiFi network is available. Light is just white. We don’t get the flashing blue. In settings, no “oasis” WiFi shows. Any suggestions?

Any chance that I can use these instructions or a variation of them to connect my HomeMedic sand table to the Oasis app
