Re: 2 concurrent while true loops?

Is this so that you can access the board at any time to get information from it? One of my control loops the remote every 60 seconds connects to the network, says that it is listening for any requests from the control unit for 5 seconds and then disconnects. This uses sockets. I didn't want to be co...

Re: ESP32 Hibernation

I found this article yesterday https://www.mischianti.org/2021/03/15/esp32-practical-power-saving-deep-sleep-and-hibernation-3/ but didn't see that it answered the question. However, when you mentioned hibernation only applied to the S2 variant I re-read this looking for the device he was referring ...

Re: compiling for 8MB PSRAM

Check if I am referring to the correct device, mine is a VIE SPIRAM variant. I copied this off a previous post, maybe search for <ESP32_SPIRAM 4MB to 8MB> a) create a partition table for that 8 MB flash and place it in the esp32 directory. The name is arbitrary. I named it partitions_8mb.csv. My cop...

Re: Crash at wlan.active(True)

For boards that I want the CP2102 running a 1000uF low-ESR cap on the 3V3 pin sorts it for me. Even using the AMS regulator.

For the remote sensors a single Li-ion cell with a HT7333 regulator and a 1000uF directly to the 3V3.

Re: ets Jan 8 2013,rst cause:4, boot mode:(3,7)

Another detail that I noticed is that the ESP 8266, besides connecting to the home network, creates another one called MicroPython-256401 that I also don't know why it appears I believe this issue is that the ESP8266 also creates an AP when booted, so try disabling that. Maybe, try: gc.mem_free() a...

Re: ESP-Now support for ESP32 (and ESP8266)

OK, thanks for that. My perennial problem of running a program where I am connected to a hotspot. If I send logs every hour everything is OK. If I wait say 24 hours in the connected-state I can log-in to Gmail's SMTP server but the data does not go. So, for both normal-WiFi and ESPNow/WiFi I keep w0...

Re: ESP01 1M Flash 512 and 1M MicroPython Neither Responds?

It has been a year or more since I played with the ESP-01, maybe this helps:

Hold GPIO0 low
Plug in USB
sudo esptool.py --chip esp8266 --port /dev/ttyUSB0 erase_flash

You got it right.

Sorry, no MacOS experience here.
