iSpindle - DIY Electronic Hydrometer

It wont boot without the temp sensor - you'll just hit a boot loop, as you're seeing there

I wanted to make sure the flash worked, because I have a bunch of boards used at school in STEM classes, I am not 100% sure they are all operational. That along with an over-supply of non-data cables (now all in the bin) and well used faulty data cables too, have caused headaches all afternoon. I didn't want to solder in an esp8266 board to the PCB only to find it not working properly. I was overthinking things after cable frustrations.

I am revisiting this to see if I can simplify the project a little to lower the cognitive load.
I am using various PCBs and previously used esp8266 units before buying in new equipment.

In the end I held the pins from the esp8266 against the solder pads long enough to get a connection and see the iSpindel WIFI and look at the data.

Thank you for your reply.

I have uploaded the iSpindel firmware but failing to get an access point. It's been a while so my memory might be foggy. I used to be able to upload the firmware and access 194.168.4.1 even with nothing connected.

I have tried flashing different versions on several esp8226 board. Each time I can only get the ESP-CA... on a wifi signal not the normal iSpindel AP. I have used the node mcu flasher and done the INTERNAL://NODEMCU and INTERNAL://BLANK before uploading firmware. I have used Brewflasher too.

This is the error message over Arduino IDE serial monitor:
FW 7.0.0
2.2.2-dev(38a443e)

I am at a loss. I am not really worried about the errors for things not yet connected. The failed to load json config I am concerned about but have run out of ideas.

You clearly have a hardware problem, probably a faulty MPU6050 (gyro) or temp sensor.

Is this kit decent? Not sure what the differences are between PCB's. I know there's also one with the mustache guy in on it, is that better?

You need to complete the build or it wont start at all. You get the json error because it has not saved any config yet

Thank you for your reply.

You could try flashing the tempmon software made by @mper as a variant of the gravitymon software it's an option in brewflasher. This doesn't require the gyro or the temp sensor as it can use the D1 mini temp sensor. This might allow testing of your D1 board.

I use this for remote monitoring of my brewfridge temperature, just need the D1 mini and battery holder and battery. You can remove the battery and charge it in a dedicated charger then replace or add the charging module if you have one lurking about.

You can use my gravitymon software as well, it will work without any sensors (you will get prompted about them missing but it will start). Unfortunately the ispindle wont start unless all the external devices is in place.
