Trying to run Micropython on esp32s3 QEMU

Hi,

This maybe a daft idea, but I'm trying to run Micropython on qemu-system-xtensa with machine esp32s3 so I can experiment with NVS encryption on secure boot without risking bricking actual devices by burning the wrong fuses on physical devices.

The emulation starts but, according to gdb, gets ...

esp_mesh with platformio

Hi,

I'm trying to use platformio to develop some code that uses esp_mesh. Sending messages from the root node to other nodes works fine, but sending to the root node always gives 4008 (ESP_ERROR_MESH_ARGUMENT).

Re: BLE mesh sensor server model pararmeter settings

I'd also like to ask the same question. I've found where these errors are reported in sensor_server.c (see below) so it's clear that the sensor definition needs an array of esp_ble_mesh_sensor_state_t and each of these need a sensor_property_id, at least one state and a raw value. However, it's not ...

Time drift on reboot

Hi All,

The clock on a esp32-cam board seems to keep good time, but after a week's uptime the clock can jump by a couple of hours on reboot. My understanding is that SetTimeOfDay sets both the RTC and the clock based on the high precision timer, but the latter is cleared on a deep-sleep or reboot ...
