Getting boot loop errors

[hammondses]

Hi there,

I'm attempting to get my Wemos D1 Mini Pro working with your bed sensor scripts, however after flashing both files I'm getting reboot errors.

I modified config.h to suit my config, should I try it with yours?

I'm really new to the whole ESP8266 thing so please be gentle :)

I have wired it all correctly (I think) SCL -> SCK, SDA -> DT, 5v -> VCC & GND -> GND from ESP to HX711. I followed the diagram provided for the weight sensors to be wired to eachother and back to the HX711.

In the Serial Monitor I get total garbage at 9600 baud, but at 115200 I get this:

ets Jan  8 2013,rst cause:2, boot mode:(3,7)

load 0x4010f000, len 1384, room 16 
tail 8
chksum 0x2d
csum 0x2d
vbb28d4a3
~ld

Any help would be greatly appreciated!

Update: Fixed my bootloop issues, issue was I needed to change the pins in the config, so now it boots but my monitor is full of absolute garbage no matter the baud I use :(

I'm actually not sure why the output is sometimes just garbage.

Did you install the Wemos Board Stuff? https://www.instructables.com/id/Programming-the-WeMos-Using-Arduino-SoftwareIDE/

I think it's because it's a knock off from AliExpress, the WiFi test module seems to do nothing which doesn't look like a good sign from what I've been reading

[Skaronator]

Could you make a picture of it and maybe link the AliExpress product?

I'm not at home right now but I'll take a picture of it tomorrow when I'm home

Weird thats a LOLIN and not a Wemos. Mine looks completly different but just checked the Wemos page and it looks like they have a new version? https://wiki.wemos.cc/products:d1:d1_mini_pro

Mine looks like this: (Notice the ceramic antenna)

I think the easiest thing for me to do is probably buy the same one you have, this is it? - https://www.trademe.co.nz/1773192104

[Skaronator]

Yes I think so but $14 is too expensive for that. This is what I've ordered earlier this year: https://www.aliexpress.com/item/WEMOS-D1-Mini-Pro-V1-0-16M-Bytes-External-Antenna-Connector-NodeMCU-ESP8266-ESP8266F-CP2104-WIFI/32861321679.html

(Just noticed that 1.0 not 1.1 but shouldn't matter)

[Skaronator]

Bascially it should be possible to run this on the v2 version but I don't have the hardware to validate this. Maybe I'll order some but it'll take almost a month until they are here.

[hammondses]

Ah, it's in NZD. The AliExpress link you gave is $11.77 so not too bad for it being local. I'll order one and let you know how I get on :)

[Skaronator]

Oh it's local? Didn't know that. The AliExpress link is $5 for me.

Edit: You probably meant total cost including shipping.

[hammondses]

Yeah, I did mean Inc shipping :)

I guess the issue too is that it's pretty difficult to find someone to test it who happens to have load sensors and the v2 hardware

I'm now getting this error after fixing the pinouts in the code:

16:52:26.210 ->

I decided to test the esp with a whole range of test sketches and it seems like all of the onboard functions are working and the HX711 calibration sketch gives me readouts of the load sensors.

After a bit of googling it seems it's quite a common error I'm getting when trying to use the hx711 and an esp8266, apparently putting in a yeild somewhere can fix it?

See here - bogde/HX711#67

@hammondses did you upload the code before connecting hx711 and the load cells? Because I am uploading the code before attaching anything onto my esp8266 and I get errors as described in your first post.

Please help.
