Shri Hari Ram G most likely mistake

Yes

I eventually was able to get the sketches uploaded to both the ESP and Mega, AND able to get serial communication going both directions (ESP -> Mega, and Mega -> ESP). Getting the serial communication working both directions lets me: -call a simple web API on the ESP, have the ESP send a serial string (command) to the Mega, and have the Mega act on the command -have the Mega read a sensor (and/or event), have the Mega rely the sensor data to the ESP, have the ESP call out to an external API to log the data I haven't had a chance to document the whole thing yet because I've been so busy with work, but if someone is in dire need of a fully working sketch let me know. I'll try my best to get what I learned posted on my blog. Now that I know how this board works, I really like it -- except for the fact that I want to run a touchscreen shield on top of it, which obstructs the DIP switches from being toggled (SMH). That's not the end of the world, but is rather annoying when coding/debugging/deploying. Arsh, once again, THANK YOU for posting this video! It was instrumental to me figuring out how to work with this board!! Hope you are well and healthy!

@@tedkrapf1302 I would very much like the code as well. I am trying to create a smart garden system and I purchased this board and getting the arduino and ESP to interact has been hard.

@@leandrosilvarodriguez6875 & @Dillan Kurtin, check out www.tedkrapf.com/Rants,Rave,Tips.aspx?article=543 for a (really terribly written) blog post, I also posted the sketches I had. I hope it helps. When I have more time, I'll try to clean up the code more and get it onto GitHub, but for now it's all the time I could spare because I didn't want to leave you hanging. Happy Coding!

@@tedkrapf1302 Thank you. I , too, have noticed this board and was interested. It is poorly documented and I have looked many places. I will write something up in great detail when I figure out the basics. Thank you for your help.

@@tedkrapf1302 Thank you very much. At first I don't know I have to write 2 codes. Thanks for that but just 1 question remains is what about tx0-rx0 or tx3-rx3. I don't get that . Otherwise the documentation is very good. I think this is much underated board . Just answer me about rx-tx

I had the same problem. In my case, I changed DIP switch to OFF OFF ON ON OFF OFF OFF OFF (atmega2560 sketch upload) When I pressed "Upload" on the IDE, I also had to click "Reset" button in the first tries. Now, it works without having to click "Reset". There are some videos on youtube mentioning this process.

@@w35l3y Thank You, This helped me.

@@w35l3y u saved my day ♥️♥️♥️

@@w35l3y yes...it required a reset....but unfortunately I did same procedure for another board ..but it not solved! Can u exactly tell me when I have to do the reset?

@@annoorkhan4219 it is not easy to identify the exact moment. You will need to try different moments for yourself. During the uploading process at arduino IDE, wait until the green bar reach +- 100% and then press reset. It might not work in the first tries. Once it starts uploading, it should be fixed and you won't need to do it anymore.
