Anyone from ESP support to point me to a solution?

Our production firmware handle to scan and connect to wifi networks to create a mesh network between nodes (it's not ESP MESH but another implementation). All things works fine until under some some conditions the nodes executes numerous scan and connections to some wifi nets. On the firmware side t...

UPDATE: We have been able to systematically reproduce the problem: 1) we set a product to normally connect to hotspot 2) we set another product to cyclically connected and disconnect to the hotspot after several connections and reconnections the problem appeared: [34.580 NoTime] Station connected to...

Aes implementation work fine unilt after an intense usage of aes module the aes encryption fail forever with this message: esp-aes: Failed to allocate memory Our products have external memory and it is mostly free, in the internal memory at least 30kb of ram are free. Some data to locate chip and id...

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...

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...

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...

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 ...

The ESP32 Datasheet is missing of a CAN-Bus chapter section. https://www.espressif.com/sites/default/files/documentation/esp32_datasheet_en.pdf https://www.espressif.com/sites/default/files/documentation/esp32_hardware_design_guidelines_en.pdf There is a more detailed datasheet? I can't find it. On ...
