Excel Data Streamer
MicrosoftESBlan Thanks for getting back to me. We have not tested Data Streamer with Parallax Propeller ( we have been testing this with Arduino, Microbit, Circuit Playground, ESP32.
We had a similar issue to what you are experiencing below with ESP32. This was caused by not using the default handshake command for RTS. The fix for ESP32 is coming out in the next release of Office ( 1911) and it might help out on your issue as well.
Leif, thanks for your response.
The Parallax modules mostly use the FTDI USB interface, so out of frustration with the Microsoft Data Streamer, the Parallax community has devised their own open Excel Data Streamer using FTD2XX.DLL with VBA. Read this thread;

This community Excel Data Streamer streamer is very robust, and as one poster comments "The FTDI DLL works well because it totally bypasses Windows".
You should sort out the Microsoft Data Streamer interface to the Parallax modules because Parallax is heavily involved in STEM education at all levels - see this website; https://www.parallax.com/education/teach

ESBlan Thanks again for the additional information. We did get a Parallax board in-house to try this out. We did replicate the same issue you where seeing, but we were able to get this working correctly when we changed the baud rate. Data Streamer is set to using the baud rate 9600 by default. You can change this in Data Streamer by going to Advanced Settings and Settings tab.
By setting the baud rate to 115200, we received data correctly in Data Streamer.
I am having a similar issue where no data is received by excel. I am using an https://www.adafruit.com/product/3857. This board is a bit different from the typical Arduino because it doesn't use a usb to serial chip but has USB support on the microcontroller itself. Maybe this is related to the issue?
I have verified data is being sent using the proper format using the Arduino serial monitor. Is there any additional debugging menus that could be added? It is concerning that there is absolutely no indication of any information being received, there is no feedback and no errors are reported.
Please let me know if there is any way I can collect debug information from excel to help diagnose the root cause of this issue.
Thanks!
