I for one would always be interested to hear about paid opportunities for ESP32 skills. I think this forum would be a good place. However, I'd suggest that needs and requirements and terms of the opportunity be clearly stated. I see too many posts on other forums that say "I have a need for an XYZ ...

I’m looking for help in planning and then implementing AWS IoT connectivity in an ESP32 based product. It’s a self funded project that I’m doing mostly for fun and learning. To be clear, this is a paying opportunity. Location: * Remote. Phone/email are ok. I’m located on the east coast of the US, in...

Great! Would here in General Discussion be the right place for that?

I have some contract work on an esp32 project, is it ok to post that here on the forum? If so, where would be the best place for that?

Thanks for the pointer here. I ended up enabling open drain on the pin and everything is working correctly now. I'm not sure if you've used the nodemcu driver but you might take a look at the esp32-owb version now that it is working.

Thanks for the pointers and the example code!

It doesn't look like the MAX3232 has any enable/disable or flow control support although maybe the digital inputs are intended for that purpose. So I'm thinking it isn't the MAX3232 causing the issue, is the other end of the device expecting flow control (a computer?) I don't see how strapping that ...

Is there hardware flow control on the RS232 device? I've seen cases where the flow control wasn't connected and depending on environmental factors, temperature, humidity etc, the floating flow control lines would cause communications to stop in one direction or the other.

Active drive is probably only a problem with multiple parasite power devices doing simultaneous conversions. But you should enable open drain mode in init either way. I'll probably add some notes to esp32-owb about the issue. I'd feel like I was doing the user a disservice if I was enabling the pin...
