Minimum NVS partition size

Hello everyone, I'd like to set up an extra nvs partition to house factory data generated via the Partition Generation Utility (https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/storage/nvs_partition_gen.html). I only need to store a handful of integers, so I setup the minimu...

Re: ESP32 Flash Download Tool V3.8.5 didn't send the reset command after the download

I downloaded V3.9.2 and I'm facing the same issue. It would be helpful if I could avoid phisically turning the power off and then on again after loading the firmware.

Hello everyone, I'm working on an application that relies on the default BLE provisioning system to get access to a WiFi network (ESP-IDF version 4.0.4).

"Unsupported detection protocol, switching and trying again"

Hello everyone, I recently setup a new development machine for ESP32 devices (Linux, ESP-IDF v4.3). Everything goes smoothly as expected and I'm able to compile and flash my firmware. However there is one additional warning that I had never seen before and doesn't come up in my usual setup (same ESP...

Re: MQTT ssl connection error

I found the issue: I was forgetting to set a specific `client_id`. Still, the error message could probably be improved.

MQTT ssl connection error

Hello, I'm trying to connect an ESP32S2 module to an MQTT broker. The connection requires SSL authentication and I have a couple of certificates to use. I copied the MQTT SSL example ( https://github.com/espressif/esp-idf/blob/release/v4.3/examples/protocols/mqtt/ssl/main/app_main.c ), removed all t...

Re: Separate provisioning and user association steps

All the required support is already available in the apps, but since this isn't the usual workflow, as of now, you will have to make your own customisations in our Android/iOS source code. I imagined this was the case. Thank you for clarifying it! I will decide in the near future whether to develop...

Separate provisioning and user association steps

Hello everyone, I'm experimenting with the Rainmaker SDK and the provided Android application with varying degrees of success. In particular I'm interested in knowing if it's possible to associate the node to a user without providing a WiFi network to connect to. Specifically I'm working with a cust...
