E13 (comm. error) on Maldives Hydrojet Pro 54173

[sergiopetruccelli]

Hi to all!
I have a Bestway Maldives Hydrojet Pro model 54173 (4 wire, Italy), I would add this remote control feature to it.

Circuit board build and ok, esp8266 flashed, webserver and mqtt works well.
But when I connect the "magic board" between CIO and DISP, after ten seconds I receive E13.

Pin declaration in BWC_82664w.cpp says this at default:
void CIO::begin() { //Setup serial to CIO here //Using hardware UART/Serial on default pins (RX/TX) cio_serial.begin(9600, SWSERIAL_8N1, D6, D7, false, 64); cio_serial.setTimeout(50); dsp_serial.begin(9600, SWSERIAL_8N1, D1, D2, false, 64); dsp_serial.setTimeout(50);
Not work as is.
In the schematic CIO pinouts says rx=D3 and tx=D2

Edited, but still not working.
Hardware I think is ok, D2,D3,D6 and D7 pin gone up with simple sketch on 8266, when up I can read 5V on relative connector pin.
There are other edit to made this fantastic project working on my 54713 Maldives Hydrojet?
Thanks in advance for you awesome job.

Sergio from Italy :)

Hi Italy!

Busy times now, but I plan to pay some attention to the 4-wire soon.

Cheers and good luck tonight

@sergiopetruccelli Congrats to both Eurovision and football victory!
Now, you are right about those pins. Amazing that anybody had this working. At least I think someone has. Anyway, I hope it's fixed in the latest update in the dev branch. I also added a simple program "serial bypass". If you have problems with E13 you could open that folder in pio, and upload. It does nothing but retransmitting the serial data. So my thoughts are that if you still get occasional E13 errors, it's hardware related.

Hi @visualapproach , Just wondering how we go about uploading the "Serial Bypass" program to test to see if this fixes our E13 errors? We can see the folder in PIO but when we upload it, it completely overwrites the ESP8266 and we no longer have wifi access to it.

[visualapproach]

@Lukey1979 it seems you uploaded it alright. If it works without E13 your hardware is ok. If not there is probably a hardware issue. Or the pump is really picky about the latency between the ports. Or the planets are not in the right configuration.
All that the program is supposed to do, is to copy data between the ports without screwing about.

Hi @sergiopetruccelli Did you end up fixing the E13 errors? if you did, what was the fix?

Hi I have a 4 wire old stile palm springs and my pinouts were different DSP (1=5V,2=TX,3=RX,4=GND) CIO (1=5V,2=RX,3=TX,4=GND) also I used an esp32 just upgrade pump to new style 6 wire so that's why I am now trying this solution.

[visualapproach]

Hi, the ESP32 won't work on 6-wire. Only 8266.

[Bishbosh02]

Ok the esp32 was for my old 4 wire controller running my own code and PCB, now that I have a 6 wire pump unit I plan to use your design (why use an esp32 when a 8266 will do the job :) ) I was going to add power monitor using ADS1115 but your already using D1 and D1 so will test how accurate the ADC or try using different pins etc.

Have the 8266 running on the bench and have order an DSP and CIO from ebay so that I can test it before striping my new pump down, my old design used Pushsafer so I could push notifications to my phone and Espalexa so that I could turn on the blower from alexa....

[Bishbosh02]

D1 and D2 :(

[visualapproach]

Hi there,
You could use other pins with some limitations. Rx/Tx could be used if you don't use serial. Not sure the CPU is fast enough to cope with fast traffic i2c while bitbanging the hot tub but you can always try.

[visualapproach]

The v2.1.4 of the code may solve this E13 problem.

Have you get it to work ?
I tested some things but it dosen´t work at the moment:(

Measure 6,9V on BLK - RED is this normal ? ( Red = GND , BLK = "5"V)

Powered ESP with Powerbank and connect the DSP -> Web IF says connected.
If i connect now the CIO with only Data the ESP only blinks .

Powered ESP by CIO without DATA an connect the DSP -> ESP blinks.

Tryed to switch DATA Cabels on CIO input without DSP connected but never get DSP active on Webpage.

In Model.h i use #define NO54173 but on the Webpage are no Jet´s visible.
I´m not sure if this part of my issue.

Not tested at the moment is Cap, Resistors an short Wires.
Use development branch from 22.4

I relay hope to get this to work 😅
Thanks in advance for your help

[Xamude]

Good to know. Then we "just" need to prevent wifi from blocking the loop.

:D
i think can live with 1 E13 in the day,when there is no fix .
Will try do add a Switch in DSP 5V Line to reset the E13 ,if this work´s, it shut be possible to add it via a Relay.

Interesting is that the E13 mostly appears between 16 & 17 o´clock
Maybe you can add a logfile that stores the data from "message" and "other"?
The logging over MQTT is not satisfactory .

Thanks for all your work to help to solve my Problems 👍

[visualapproach]

@Xamude check out the new code in development branch. I pulled the fork (can you eat pulled fork??) from #304. You are welcome to test it and see if it helps with your E13. Thank you @cobaltfish

[Xamude]

Good Evening,
Tested the Firmware: 4W_2022-06-27 without E 13 Errors an 3 day´s that´s great :)
(test only on the weekend so i can reset the beep )

Problem is now that i get an En8 error and beep :(

and the other one is that the esp stops good mode and the pump..
had this ~ 7 times today

EDIT:
other interesting thing: God & Pump active, when i open the WebIf God/Pump goes off

[visualapproach]

Is the error shown on the pump display? 'En8'?

[visualapproach]

@Xamude I made a very small update to the dev branch now. Before: if cio send a message with an error flag AND a bad checksum, we disarmed godmode. Now: we don't care about the message.

[Xamude]

Yes it's on the Display.
Will update later.
Seem's we are on the right way to get it to work :)

[Xamude]

Sorry for the late response, had not much time to test it.
in 4 Test Day´s i got 3 En8 Errors
and 1day E01
but still no E13 :)

[visualapproach]

I don't know if it applies here, but @SigmaPic found out in another thread #330 that pins D3/4 was no good as inputs. I wonder if it would help to use other pins here too.
In that case you should move the wires going to d3 and d4 to for instance d5 and d6. And then edit pinout accordingly in the code
