I saw this but this seemed as problem with espsecure.py digest_rsa_public_key writing reverse order bytes but I observed that byte order was ok for me.
Just tried that patch and it worked on esp32 where i burned BLOCK2 previously.
Thanks for help

Re: Problem with Secure Boot V2 enabling
Turns out it isn't read protected but bootloader isn't responding to UART after SecureBoot V2 and Flash encryption enabling. Can't read any efuses or upload anything using bootloader. I took next module and flashed with software that reads BLOCK2 and it is exactly the same as on those 2 modules wher...

Re: Problem with Secure Boot V2 enabling
OK i successfully enabled SecureBoot V2 by alowing bootloader to burn secure boot digest to BLOCK2
This is kind of OK, but I don't understand why manual digest burning didn't work. I can't see the values burned by bootloader now after Secure Boot and encryption are enabled.

Re: Problem with Secure Boot V2 enabling
@WiFive Using ESP-IDF v4.2-0-gc40f2590b I noticed reading SB2 documentation is that there is no word about when and how SB2 key is burned in efuses: https://docs.espressif.com/projects/esp-idf/en/v4.2/esp32/security/secure-boot-v2.html#secure-boot-v2-generate-key Can it be that bootloader contains d...

Re: Problem with Secure Boot V2 enabling
Can anyone help?
Did same thing with next ESP32-WROOM-32E module. This time only efuses changed are BLOCK2 and it's write protect, nothing else touched and still getting "Application not signed with a valid private key"
Any advices what to try?
Am I generating or writing key incorrectly?
@ESP_Angus ?

As far as my experiments show that modem sleep is not working in AP mode and STA mode when not connected. Can you suggest if there is a way to enable modem sleep in unconnected STA o...

Re: BLE custom profiles with security
Thanks @chegewara! I will look closer at links you gave but at first look I see that attribute handle is read in ESP_GATTS_ADD_CHAR_EVT event. But if I use esp_ble_gatts_create_attr_tab() i get ESP_GATTS_CREAT_ATTR_TAB_EVT event and I am not sure how to extract handle for each attribute because i ge...

So I am looking in way of combining examples from IDF folder: gatt_security_server, gatt_security_client, gatt_server, gatt_client, because security_server/client applications are made ...
