Hi,

What cellular modems work well with the ESP32? Most of them are designed for the Raspberry Pi. Very few even mention the ESP32.

Which ones have worked with the ESP32 and can be recommended?

Thanks,

Hi, What is the best way, or is there a way, to set a value in a parent Kconfig menu and have it available in a subordinate component Kconfig? In other words, how can I set a variable in the parent Kconfig and have it available in the component Kconfig? For example, I want the WIFI_HOSTNAME "Foo" to...

Hi, I am having trouble getting git-only components to update in my projects. ### Background: I have several private components on git that I add to my projects by editing my project `idf_components.yml` file. After running `idf.py reconfigure`, a new component is added to my `managed_components` di...

Hi, I'm having problems with OTA firmware verification prior to reboot. Here's the process I'm following: 1. GitHub builds the firmware image and calculates a SHA-256 checksum. 2. The file is then saved to an AWS S3 bucket. 3. During OTA, the firmware is copied from S3 to the ESP32. 4. On the ESP32,...

The am312 obviously works in C because MicroPython works (which is written in C). So, wtf? You could try disabling the ESP's pull-up resistor. Datasheets seem to imply that the sensor doesn't need it. Tried the disable. The behavior is better, but not yet fixed. There are still random "motion detec...

Great point! I'll try that.

Thanks!

Apart from the overflow of FreeRTOS's tick count after a long time running which isn't really handled in the debounce logic, and the use of ESP_LOGx inside an ISR which should be avoided, the code looks all right to me. Could you be having an issue with wiring/an unreliable connection (breadboard?)...

Hi, Does anyone have a code example of the am312 PIR sensor? I've found them to be very reliable in MicroPython, but I can't get them to work in an ESP-IDF/FreeRTOS app written in C. Keep getting random motion detection for no reason (even when the sensor is completely covered). Since this PIR senso...

Hi,

Does anyone run RainMaker on AWS? Is it expensive? Would you recommend it?

Hi, Has anyone succeeded in creating their own registry? If so, how? I've been going over the docs and it isn't clear if that's possible. Basically, I want to have my own collection of components to pull with `idf.py add-submodule`. Or, should I just create component repos and add them as submodules...
