The form factor might be right but its not pin compatible with the esp8266. They have put the 3.3V where the SCL needs to be. Would require a new pcb to work.

Here is the link to the project; https://github.com/mp-se/gravitymon-blegw, i've also added it to brewflasher (Gravitymon Gateway). Default wifi password is same as for gravitymon and the UI is more or less a subset of that project so most of that documentation should apply to this project as well

Perfect, I will make the project public and publish a build. I guess you are using the ESP32 PRO which will work with the extended and service options but not EddyStone since that requires BLE 5. I found that an ESP32S3 PRO can be used which I'm currently testing myself. I have added support...

The idea behind this project is to use existing hardware with modifications. Since there are a lot of available pcb options for building an ispindel with the MINI formfactor then it's quite easy for someone to build an version with newer hardware. But if someone creates a pcb for the mini...

Does anyone use the BLE feature on Gravitymon with a ESP32C3 or ESP32S3? I have been working on a feature for tiltbridge that can handle the new data formats and relay those to a server using HTTP. Currently its a standalone software but the intention is to integrate it into tiltbridge once I...

I dont think it comes in a mini form factor like the c3/s2/s3 (or I have not seen it). I prefer the s3 mini which works much better. Its not a problem to support more cpu's but it also needs to fit existing pcb and have the same formfactor as d1 mini.

Looking forward to your findings

Is anyone using an esp32 version with bluetooth? I want some feedback and experiences from using that.

That should work fine, it has been raining all weekend here as well. So finally some time to do coding and brewing!

You can just install it on a esp without sensors, it will work but you will get some warnings.

A new UI test build https://github.com/mp-se/gravitymon/releases/tag/v2.0.0-alfa4 I think i have fixed all other things that have been mentioned here but let me know if I missed anything. I still have a few issues to sort out, the following are things to address: * Validate the configuration...

There are two different options for bf, ispindel and custom stream. It might be that you have the wrong format for the target. I just tested the ispindel options and that worked fine.

From what I can see in the logs it seams to send the data as in the format template. I found an issue when storing the template so that could be the cause. When doing the testing it can be helpful to open a second window with a serial console so you can see what is going on. The MQTT logs would...

I will take a look on the mqtt part, it should be visible in the serial console what data is sent and to what topics. Under other -> tools you can browse the file system and the format used for mqtt is in the file mqtt.tpl I have noted that backup is not working on the device, this seams to be...

Should not be a problem. I have changed the configuration format in 2.0 but the device should migrate the existing settings to the new format. Will have a look at that part. This narrows down the search to thanks for the update. You can always do a backup of the settings and store them if needed.

Hmm, the configuration should be persistent so I will look into what could have happend there... And since the UI and Arduino code are two separate github projects they have different version numbers. I should make that more clear in the UI. Firmware vs UI Version or something.

New alfa with the reported bugs fixed. https://github.com/mp-se/gravitymon/releases/tag/v2.0.0-alfa3

Good find, actually none of the testing functions worked, I had a mismatch in the VueJS code and Arduino. I will do an update tomorrow.

Well, the device probably went into sleep mode so I have added some code to detect that and show a message to the user that there is no response from the device or you can do a lot of changes without having the ability to save them. Will do an update probably tomorrow.

Well if it was calibrated at 90 degrees and you moved the device it will go into sleep mode unless you toggle the switch on the front page. Thats probably why you lost connection
