ESP-HOSTED and SDIO clock speed above 25Mhz

Greetings, I apologize in advance, I do not see an esp-hosted specific forum. So I will try here, as it seems related to the SDIO slave module within esp-idf. We are using the esp-hosted solution for a WiFi and Bluetooth solution with a Linux host. We have not found that our throughput matches the p...

Possible bug in crosscore_int.c missing IRAM_ATTR in function esp_crosscore_isr_handle_yield

I can reproduce an unexpected exception trying to use esp-idf ota ops. My code is calling esp_ota_begin() which in turn erases a partition of the flash. The other core at this time is handling an rf protocol with interrupts, which are marked with IRAM_ATTR to ensure that they run from ram. However, ...

Problem reading PID key from bonded device list using GAP ble API

I am trying to add devices to a white list. Some of the devices are using privacy mode, which means they are changing their address frequently. So I cannot just add the last bda to the white list.

ESP_GATTC_REG_FOR_NOTIFY_EVT should include bda in parms in ble stack

I am connecting an esp32 to multiple identical peripherals and I am registering for notifications for 2 characteristics from each one. In the ESP_GATTC_REG_FOR_NOTIFY_EVT, I only have access to the handle and the status. Shouldn't I also have access to the bda that has been registered since when I r...

We are experiencing frequent but intermittent crashes after the first few seconds of our board initialization. We are successfully initializing wifi and ble, connecting to a remote wifi AP, and 3 ble peripherals. However, we are occasionally seeing the following exception: Guru Meditation Error of t...
