What am I doing wrong? MR60BHA1 sensor on Seeed-ESP32c3
Given:
1 x Seeed MR60BHA1 sensor
1 x Seeed-ESP32c3 (XIAO)
1 x UART USB Adapter
1 x PC
Wanted:
Use MR60BHA1 sensor with ESP32c3
(later the ESP should write the heart and breathing rate into a HAPI-FHIR server via FHIR (REST in healthcare)…)
My approach:
1.) If I connect the MR60BHA1 sensor to the PC via the UART USB adapter, the seeed demo program displays the heart and breathing rate; So the sensor works; The latest firmware is also on it
2.) I load my own software onto the ESP32c3, the ESP also works great and sends the data to my REST server via http-POST via WLAN; So the ESP32c3 works too
5.) Compile and load the original seeed sketch (MR60BHA1_Breath_heartbeat_inf_output.ino) onto the ESP32c3 via USB, this also works. The message appears: “Leaving…Hard resetting via RTS pin…” and open the “serial monitor” of the IDE…
Comes my problem:
The error message: “Timeout. The IDE has not received the ‘success’ message from the monitor after successfully connecting to it. Could not connect to COM5 serial port.”
If I pull the USB cable out of the ESP32c3 and plug it back in then Windows reports a faulty USB device. Pressing the RESET button on the ESP32c3 doesn’t help either. After correctly pressing the REBOOT sequence, the ESP32c3 is found again by the operating system and the IDE but the sketch does not run (I think).
Does somebody has any idea?
Thank you for your help and greetings from Berlin!

Hi there , If I may.
So under NORMAL Compile and upload scenario Only setting the right board and port and the IDE does the rest no buttons to touch or push. After a Bad Code upload (i.e. the code is bad) but upload is fine as Normal, After resetting the result is a boot loop or other unexpected behavior. (maybe over-wrote some bootloader memory location or something out of bounds) in any case Now trying to upload a fixed code or Know good code The IDE and Chip are not syncing and acting Normal.
NOW the only uploads that will work require the buttons to get it in the Mode.
Can you get the prompt like What I get if I hold the boot button down and tap and release the reset button?
My Serial monitor looks like this output (note the last line?)
ESP32 Chip model = ESP32-C3 Rev 3
This chip has 1 cores
Chip ID: 4170632
ESP-ROM:esp32c3-api1-20210207
Build:Feb 7 2021
rst:0x15 (USB_UART_CHIP_RESET),boot:0x0 (USB_BOOT)
Saved PC:0x400462dc
**wait usb download** <--------**
Try that and upload again. Your close.

ps. Here’s the Basic Known good Upload I use when things get funny…
/* The true ESP32 chip ID is essentially its MAC address.
This sketch provides an alternate chip ID that matches
the output of the ESP.getChipId() function on ESP8266
(i.e. a 32-bit integer matching the last 3 bytes of
the MAC address. This is less unique than the
MAC address chip ID, but is helpful when you need
an identifier that can be no more than a 32-bit integer
(like for switch...case).

// Test code to get chip ID and STUFF

int Vibration_signal = B10;
int Sensor_State = 1;
void setup() {
Serial.begin(9600);

here is the compile output. just FYI.

Thank you very much for your help, especially PJ_Glasso and Citric.
Apparently it was the source code of the seeed-example program itself. In the Wiki (>>> Pin Multiplexing | Seeed Studio Wiki) I found another variant with “PIN multiplexing” and it works perfectly (no faulty USB device and Heartbeat in the terminal/serial Monitor).
