Some Clarification on Mesh
I'm reviewing the code to prepare it to production stage and I need some clarification on Mesh working. I implemented Wifi mesh using IDF (not MDF) and it work very well but I need to understand some things: 1) I'm using IDF API and not MDF API, there is some reason to move to MDF like IDF major ver...

Re: [ESP32-S2] Wifi APSTA/STA switch rebotting issue
I found the problem. I implemented a Init\DeInit procedures for wifi to switch from AP mode to Station mode. The problem was with creating the standard wifi AP and then destroy it. static esp_netif_t* ap_ntptr = NULL; in the init: ap_ntptr = esp_netif_create_default_wifi_ap(); in the deinit: esp_net...

Re: [ESP32-S2] Out of control rebotting issue
Hello, thank you for the replies, this not happen when the product starts, but sometimes, maybe after a bug, the firmware reboot and go in that state. If I press the reset button it will start normally. I have a custom pcb programmer based on FT2232 chip with reset button and an automatic download m...

Re: CAN transceiver Pinout on ESP32
I was wrong with that GPIOs because I use a module with PSRAM. I forget to check also the module datasheet: https://www.mouser.it/datasheet/2/891/esp32_wrover_e_esp32_wrover_ie_datasheet_en-1855913.pdf I moved my GPIO: CAN_RX on GPIO18 CAN_TX on GPIO19 and in another product, same module but I have ...

Re: the biggest issue with the esp32 is the ide and build system..
I noticed same problems, ESP32 family lacks a serious IDE, a good build system and a decent debug experience to be at the same level of other microcontrollers. From one side I think it's the only MCU on the market that combine the specifications to run Wifi, Tcp, SSL stack etc.. with powerful API's ...
