Hi All,

only a tip if you are doing this kind of thing, As Neil said, is not possible to use the serial monitor and upload at the same time.

As an alternative for that I use a software called screen, which is a terminal emulator ( for Linux and Mac OS).

Doing so, you can upload and monitor in your terminal what is returning from the serial monitor.

You only need to open your terminal and type:

$screen /dev/cu.YOUR_SERIAL_PORT 115200

Hope this help someone.

cheers,

Vicente.

This looks very interesting and useful. My desk is a rats nest of wires and being able to programme OTA would be really useful. However, I think I will have to leave it for later as I have other things (mobile robots) that I want to work on first.

OTA is a wonderful thing when it works. I worked on a zigbee mesh configuration where we could have several 100 devices on a channel. Using a OTA scheme to update the firmware was a lengthy process, but it was much simpler than updating each module, one at a time, with a JTAG programmer.

We ran into similar issues, regarding memory sizing, but solved the problem with a serial epprom/flash to hold the temporary copy.

Great blog!

Nice post. I had not looked into OTA updating before as I haven’t had a need for it. It will be very useful for developing remote sensors.

I think I’ll try it with an ESP32cam that I have that doesn’t like being powered via the computer USB port (brownout detection gets triggered when WiFi is active).
