Getting the following error when attempting a compile using ESP32 Dev Module:

C:\Users\can77\Downloads\Zimodem-master\Zimodem-master\zimodem\zimodem.ino: In function 'void changeBaudRate(int)':

zimodem:291:17: error: expected unqualified-id before '.' token

HardwareSerial.changeBaudRate(baudRate);

             ^

C:\Users\can77\Downloads\Zimodem-master\Zimodem-master\zimodem\zimodem.ino: In function 'void changeSerialConfig(uint32_t)':

zimodem:305:12: error: 'class HardwareSerial' has no member named 'changeConfig'

HWSerial.changeConfig(conf);

I have the same issue.

I'm guessing the instructions in the README were not followed?

I don't think I missed anything. I should have included more details and the full errors. I'm building on a Mac and I'm using Arduino 1.8.13. I've changed the files listed for the ESP32. These are all the errors:

zimodem:286:40: error: 'void changeBaudRate(int)' was declared 'extern' and later 'static' [-fpermissive]
static void changeBaudRate(int baudRate)

I was able to get it to build but it doesn't work. I removed the Arduino environment completely along with all the libraries and source files, then reinstalled the Arduino IDE and the ESP32 core from github (stable release) as detailed here:

https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide/boards_manager.md

I then applied the changes listed. The only difference from before is where I put the lines in HardwareSerial.h.

After that I could successfully build and upload. However on reset all I get on the serial monitor is output at 115200 of:

Reset complete. Init start
Init complete.

At 1200 baud I get nothing.

Was there ever any resolution to these issues? I have run across the same and am wondering if anyone figured it out.

bozimmerman commented

So, are the compile errors identical?
My only guess is that maybe they changed something about the compiler along the way? I'm using Arduino IDE 1.6.11 still..

Also, perhaps someone more familiar with the market can explain something to me: I would have sworn the NodeMCU was an ESP 8266 package, not an ESP32 package. Am I way off? Thanks!

Bo, thanks for responding: I used the version from your notes: "To build this firmware for the ESP-32, I also used the Arduino IDE rev 1.8.10 with the Arduino ESP32 Dev Module installed from the board manager" - on windows 10. I keep getting the 'class HardwareSerial' has no member named 'changebaudrate'. I did try updating to the latest version but using your changes in the notes, but got a ton of errors. I need to revert back to 1.8.10.

The device I have are labeled: NodeMCU ESP32-S and I got them off Amazon.

Thanks for making this firmware - I use it on the ESP8266, and it is great!

Can you double-check HardwareSerial.h has the void changeBaudRate(int baudRate);.
If it does, then it must not be looking at the same HardwareSerial.h you think it is. In which case, check the arduino ide docs on how to turn on compiling command line echo. In mine it's under File/Preferences-> "Show verbose output during [X] Compilation".

Then, when compiling, you'll see lines like this:
C:\Users\Bo Zimmerman\Documents\Arduino\hardware\espressif\esp32/tools/xtensa-esp32-elf/bin/xtensa-esp32-elf-g++" -DESP_PLATFORM -DMBEDTLS_CONFIG_FILE="mbedtls/esp_config.h" -DHAVE_CONFIG_H "-IC:\Users\Bo Zimmerman\Documents\Arduino\hardware\espressif\esp32/tools/sdk/include/config" "-IC:\Users\Bo Zimmerman\Documents\Arduino\hardware\espressif\esp32/tools/sdk/include/bluedroid" ...........

The trick is to look and see if the directories on the -I bits matches where you found HardwareSerial.h. You may have to copy/paste a line into notepad and turn on word wrap to see all the lines.

Let me know!

Closing this for lack of communication (and not being able to repro). LMK if something changes.
