- Mon Sep 10, 2018 6:44 am #78170 Thanks for your help. But I tried it several times and i get success messages but no answer sending the hex strings. I am sure the hex code is the right one from https://www.esp8266.com/viewtopic.php?p=74262#p74262 since i can see your name in the last couple of bytes.

Here is the output from flashing

Below two screens from the programming software (one with loaded Buffer shown, one with COM Helper), i'm not sure if i need any EEPROM data or if my settings are correct. Its all on default. In the COM Helper window you can see the RXs increment, but no TX or LED flashing

Under normal circumstances i never let fear and good judgment stand in the way of a hearty laugh. ~AvE

- Sat Dec 15, 2018 6:27 am #79578 Is it possible to get the source code for the 15F104W?

regards

- Sat Dec 29, 2018 8:36 pm #79772 Hello, I have a similar problem with the 2ch version of LC Tech (LC-Relay-ESP01-2R-5V) . Instead of stm, they use a Nuvoton N76E003 MCU.

With the ESP-01 connected or not, after about 30 sec, the led D6 flash (0.5s) and I tried every solution without any success, I think we should flash the firmware of N76E003, but where to find it ?

Thanks,

4.The program must be transferred to the module. It is necessary to think to cross the cables TX RX and one does not branch 5V power supply.

With the programe STC-ISP.exe we load the proramme .hex, we set the clock at 11.0592 MHz, and press the button DOWNLOAD / PROGRAM, Connect the 5V power supply of the module and wait until the transfert is finished.

Hello - first of all, thank you so much for creating a solution for these bloody modules

I am hoping that you have some advice - my unit definitely has the STU-15F104W MCU, but I can't follow the step quoted above; my unit, whenever the unit is powered up, I see the D2 LED (blue) flashing non-stop, but I do NOT hear the relay clicking at all.

When I hook up the STC-ISP unit and attempt to push the .hex code through, the software goes no further than "Checking target MCU ... ". While I wait for anything to happen, I can see the TX LED is solid - and I see some activity on my FTDI TX light, but this TX activity appears to be only reflecting the D2 LED on the relay unit...

I have two identical relay units with the same problem. Am i missing a basic step?

Many thanks for any advice!!
