What is error 102? I can't seem to find what this error is and how to prevent it from happening. https://github.com/espressif/esp-idf/blob/release/v5.1/components/bt/host/bluedroid/btc/core/btc_dm.c#L275 The define block only goes to 94. #if (SMP_INCLUDED == TRUE) #define BTA_DM_AUTH_FAIL_BASE (HCI_...

Do you have any example for that?
Bonus if there are multiple tasks that need to read I2C values in addition to the GPIO interrupt.

It may be the way I am handling the interrupt. I will change it to see if I can resolve the issue. The interrupt is triggered on GPIO, and I am reading I2C inside the interrupt handler. I will move it out and hopefully this goes away. It doesn't happen all the time. In fact, I would say 99% of the t...

Can someone please help me understand what happened on this crash? Guru Meditation Error: Core 0 panic'ed (Interrupt wdt timeout on CPU0).

Hi, I have been having issues with bonding keys being MIA and I started digging around. According to btc.dm.c line 280, the default action for a failed secure bonding connection is to delete the bonding keys. https://github.com/espressif/esp-idf/blob/master/components/bt/host/bluedroid/btc/core/btc_...

Hi, I am using bonding with JustWorks, but I would like to only have one bonded device and refuse any other attempt of bonding. How do I accomplish that? Here is what I have: esp_ble_auth_req_t auth_req = ESP_LE_AUTH_REQ_SC_BOND; // bonding with peer device after authentication esp_ble_io_cap_t ioca...

Hi, I can't seem to find what fail_reason 0x66 is. Where can I find a description of this error or get more details on how it was raised so I can investigate the problem I am experiencing? This is the code that is returning the error: case ESP_GAP_BLE_AUTH_CMPL_EVT: { esp_bd_addr_t bd_addr; memcpy(b...

I am using chip rev3 on esp-idf 4.2
I PM'ed you the code.

Hi, I am experiencing very slow processing after I enabled flash encryption. It's very clear on my I2c communication. Here is a screenshot before: before.JPG And here is after: after.JPG The total time for the entire I2C communication was less than 10ms before. It is now over 30ms It gets much worse...

I have used a chip Rev3 for secure boot V2 and flash encryption and indeed the download UART fuse gets burned automatically now. It doesn't allow me the brick the chip anymore. I have another question on this though. If I have the chip locked and OTA is the only way to get new firmware into the chip...
