Netif with wifi in APSTA mode
Hello all, I'm configuring wifi to be in APSTA mode to run a webserver. One question I have is when I use esp_netif_init(), can I use esp_netif_create_default_wifi_sta() and esp_netif_create_default_wifi_ap() in sequence to have the netif interface automatically configured, or do I have to handle th...

Re: ESP32 ECP Keypair JWT header formatting
Sorry for the long time to get back - some things came up. I went to the lab and found that when I write out the private X and private Y of the ecp keypair using mbedtls_ecp_point_write_binary, the binary strings are in fact 256 bytes long, and the last 32 are always hexadecimal pairs. I was not pri...

Re: ESP32 ECP Keypair JWT header formatting
Are these last 64 or 66 characters the hexadecimal octets I should be concatenating to form the JWT signature? They should be. However, each value must be 256 bits, i.e. 32 bytes, i.e. 64 hex digits. Not sure why you're getting 66 (=33 bytes). Alright, that's what I figured but I wanted someone wit...

Re: ESP32 ECP Keypair JWT header formatting
Does https://esp32.com/viewtopic.php?f=13&t=19875 help? I solved the first question (it should be private_X and private_Y by the documentation). Not exactly. Their example uses RSA, I *have* to use ECDSA and the issue with this is the conversion of the ECDSA signature into octet sequences to then b...

ESP32 ECP Keypair JWT header formatting
Hello all, I am using an ESP32 to connect to a server and send a JWT. I am using the ES256 algorithm to create a JWT using mbedTLS. I just had a few questions as I am new to cryptography and mbedTLS on the ESP32, and wanted to ask if any users have experience using mbedTLS on ESP32. For the x and y ...

Re: Monitor printing unreadable output
Sorry for getting back to this so late, but it happens if you install any ESP command line tools after you install the ESP IDF VS Code extension. It may also occur if you use the direct command terminal rather than using than using the ESP-IDF terminal.

Re: Monitor printing unreadable output
Seems your serial port gets opened at 460800 baud; by default the ESP32 outputs data at 115200. (Note that flashing can be faster than that.) Maybe a setting somewhere? Hello Sprite, I tried your suggestion and it still handled the same way, but thanks for the advice. What's interesting is instead ...

Monitor printing unreadable output
Hello all, My first time posting here so hope this is the right forum. I am running an ESP32 from COM4 on Windows 10 64 bit in VSCode using the ESP-IDF extension with Python 3.11 and ESP IDF Framework 5.0.1-2. I followed the tutorial here https://esp32tutorials.com/install-esp32-esp-idf-windows-inte...
