2038 year problem

Hi there, I'm doing some test with sntp and date-time handling and I've found tha the newlib mktime and time functions suffer the 2038 effect problem. I've done a little test for my system and there it is struct tm tm_time; time_t epoch=0; struct timeval tv_time ; char strftime_buf[100]; setenv("TZ"...

Re: Tests with silicon V1

hi I use ESP32-D0WDQ6 provided by distributor in south Europe, ASTONE. image1.JPG I've confirmed through efuses that it is V1. Then, I'm using it replacing the V0 version ESP32-D0WDQ6 of a ESP-WROOM-32. Then the module is running on a proprietary board and checked that all other functionality is wor...

Tests with silicon V1

Hi, I've finally received samples of ESP32 V1 and I've been testing their response to browout. I've modifyied kconfig to enable brownout and set BROWNOUT level to 2.1 V and delay to the maximum. With this silicon now I'm able to see the BOR and RTCWDT_BROWN_OUT_RESET but in my tests I'm being able t...

socket api

Hi there, I'm using the socket api to be use to reuse some code and I'm finding that the sockets are single use. As far as I've seen until now (some more investigation needed) the sockets have three possible states https://github.com/espressif/esp-idf/blob/master/components/lwip/api/sockets.c#L223 F...

Re: How to Visually Tell New from Old Silicon?

hi rudi ;-)
the ESP32-D0WDQ6 sample came from distribution as silicon version 1 and I've replaced into a ESP-WROOM-32 module.
the piece marking says 012017 , PC3W29. Apparently the manufacturing week doesn't ensure being V1 but, from ESP_igrr words, prior to that there were some pieces manufactured.

Re: How to Visually Tell New from Old Silicon?

nvs key_name problem

Hi there, I'm trying to implement a flash log of relevant events using nvs api. The idea was having nvs namespace were events are stored sequentially and then they can be retrieved when required. For that I've set a name pattern, like "entryXX" where XX is the number of event. So each time a new eve...

Re: error loading PHY init data

Maybe something missing in the initialization, being GPIO36 and GPIO39 and they are meant to be SENSOR_VP and SENSOR_VN?
