Re: Creating a mesh network without a router connected

I presume you do not want or have a WiFi available but still need a mesh. I had a similar requirement, for example if you are going to use LORA instead of WiFi, or just collect data an store it. Anyways, what I ended up doing is using another ESP32 in STA mode so that it will provide the REQUIRED Wi...

Re: React to GPIO fast: ISR or queue?

I suggest having a setup routine that sets the gpio as input and adds it as isr int. Call it from within the ISR after setting it for output. I presume you are not making a delay within, just gpio_ser_level(pin,1) and then gpio_set_level(pin,0) basically a pulse.

ESPRainmaker OTA Fail in IDF V5 but not in V4.6

Hi. Does anybody know if there is a “general” OTA update problem in IDF V5.0.2 with ESPRainmaker? I have an App using rainmaker in V4.6.6 and it works PERFECTLY when making any code change(or just version) and using ESPRainmaker Dashboard to start an OTA job, always finishing with SUCCESS. The chang...

Re: Is there support for MDF

Their lack of interest could be due to MATTER or Thread as an alternative but they wont state that due to losing credibility in the policies they made and the difficulty of explaining to many developers that they are abandoning them. Anyway, better forget anything related to esprainmaker due to thei...

Re: Cannot flash custom PCB

Thanks for the explanation. This issue happened to me with AMS1117 and ESP32-Wrom, ESP32S, ESP32C, so maybe something in all my PCB designs is at fault. Ill check it out.

Regards.

Re: Cannot flash custom PCB

From personal experience same problem, the RESET (EN) pin does not need a Cap. Take out the Cap C11 and it will work, without any PCB change. Try it.

Re: ESP-32 Modbus RTU master and slave istances simultaneously

Hi. I actually did not try what I’m about to explain but I have done a lot of programming in espidf/Esp32xxx and from the espidf examples (google it) in protocols/modbus/serial you have a Master and Slave example. You will see that the Master and Slave have a configuration section in where the real ...
