Hi Italy! Busy times now, but I plan to pay some attention to the 4-wire soon. Cheers and good luck tonight |

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. |

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

Have you get it to work ? 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. 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. Not tested at the moment is Cap, Resistors an short Wires. I relay hope to get this to work 😅 |

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 :)
