  Back in school my friends all flashed their mcus with 4-8MB images over serial with 115200 baud. I set up ota updates over wifi. They were all fascinated by my speedy flashes. However when I offered to help them set it up not one was interested because their setup was working as is and slow flashing is not a “bad” thing since it gave them an excuse to do.other things.

    You’ve convinced me to learn and implement OTA on my 8266. Thanks!

      I used this script:

      import Axios from 'axios'
      import OldFS from 'fs'
      import { PromiseChain } from '@feather-ink/ts-utils'
      
      const fs = OldFS.promises
      
      const image = process.argv[2]
      const destination = `http://${process.argv[3]}/vfs/ota`
      const now = process.argv[4] === 'now'
      const once = process.argv[4] === 'once'
      
      async function triggerUpdate(): Promise<void> {
        console.log('Uploading new binary')
        const file = await fs.readFile(image)
      
        await Axios({
          method: 'POST',
          url: destination,
          headers: {
            'Content-Type': 'application/octet-stream',
            'Content-Length': file.byteLength
          },
          data: file
        })
        console.log('Finished uploading')
      }
      
      (async () => {
        const updateChain = new PromiseChain()
        console.log(`Watching file '${image}' for changes\nWill upload to '${destination}'!`)
        if (once) {
          await triggerUpdate()
          return
        }
        if (now)
          await updateChain.enqueue(triggerUpdate)
        OldFS.watch(image, async (eventType) => {
          if (eventType !== 'change')
            return
          let succ = false
          do {
            try {
              console.log('Change detected')
              await updateChain.enqueue(triggerUpdate)
              succ = true
            } catch (e) {
              console.error(e)
              console.log('Retrying upload')
            }
          } while (!succ)
          console.log('Upload finished')
        })
      })()

      Hahahah. Awesome. Have fun! You just need a simple webserver. The builtin one will do and then you use the ota functions of the ESP IDF.
