Re: Stuck with the esp-modem component

Yes it works ok in other environments and in this comment https://github.com/espressif/esp-protocols/issues/352#issuecomment-1715291889 on the issue you can for example see its receiveing AT commands and return OK: D (1173) command_lib: generic_command command AT+CGDCONT=1,"IP","iot.1nce.net" D (131...

Stuck with the esp-modem component

We're trying to use the esp-modem component (https://github.com/espressif/esp-protocols/tree/master/components/esp_modem) with the goal of using it with a secure TLS connection with the "Digital Signature with ESP-TLS" support, but so far not getting very far and blocked with several problems with t...

Re: DS Periperal vs Secure Boot

Is it possible for a hacker to gain cpu execution privileges? Asking the other way around: How certain are you/can you be that in a complex application with tens of thousands of lines of code compiled in, possibly accessible over network and other interfaces, there is no spot where a buffer overflo...

Re: DS Periperal vs Secure Boot

Over here its said: "... ESP-DS is much more secure because the keys are entirely inaccessible to software. 'C' code usually has plenty of software exploits, and a motivated attacker can often gain cpu execution privileges " - https://github.com/espressif/esp-idf/issues/11270#issuecomment-1523000011...

DS Periperal vs Secure Boot

We've been looking at using the Digital Signature Peripheral and struggling to get what we want to work. Are there any examples somewhere showing how to do on chip key generation instead of using the tooling on a host to generate/upload keys? That aside, what are the advantages of using the DS Perip...

espidf-http-request example - DNS lookup failed err=202

Hello, I'm trying to get an espidf-http-request example working but it always fails with DNS lookup failed err=202. Its actually a [url]platformio example[https://github.com/platformio/platform-espressif32/tree/develop/examples/espidf-http-request] but otherwise looks like a fairly simple IDF exampl...

Re: BLE and WIFI simultaneously

There is this: https://developer.ibm.com/recipes/tutorials/experiments-with-bluetooth-and-watson/ but it is broken with the latest IDF code, and it never really worked very reliably always eventually failing with this: https://github.com/espressif/esp-idf/issues/442. After that I tried updating IDF ...
