Bootloader offset

I'm using ESP32-S3, ESP-IDF v.6.0.1 and batch file for compilation and flash esp-idf project.
I'm confused what offset value shoul be used for programming bootloader.bin with esptool.
Offset 0x1000 doesn't work
esptool --chip esp32s3 --port=COM%1 --before=default-reset --after=no-reset write-flash ...

Re: Receiving WebSocket data

Thank You for response.
You are right with “The <CR><LF> belongs to the end of the previous message and was not fully consumed or handled by the MCU side”
I think this is the reason, that I missed:

Re: daylight saving time

Sure, UTC is available in LTE module but it was more convenient in my usecase to use local time adjusted and marked with DST flag by operator.

Unfortunately after migrating from LTE to ESP had to change RTC maintenance since there was not live DST available.

This is little more complicated in my ...

Receiving WebSocket data

Is it possible to receive information that data are waiting in module buffer and then read it?
Or data streamed together with commad is the only way?:
+WS_DATA:0,4,test

I think that this form of binary data serving + problem with additional <CR><LF> before "+WS_DATA:" message that appears ...

Re: daylight saving time

Thank You @lbernstone for answare.
Upon further consideration, ESP provides time from an SNTP server (UTC). If we configure a time zone, it's the local time (e.g., UTC+1). The LTE module, on the other hand, returns the operator's local time, which already takes into account the offset related to ...

daylight saving time

Is available information that daylight savings is in effect?
Main device need to know this information.
I see only: +CIPSNTPTIME:Tue Nov 25 12:31:21 2025<CR><LF>
Is available any other format of data?
E.g. in other module (Quectel) is:
"2017/01/13,11:41:23+32,0"
that last value shows adjustment (0 ...

Error in documentation?

There is:
Improve UART TX and RX throughput

uart_driver_install(esp_at_uart_port, 1024 * 16, 1024 * 16, 100, &esp_at_uart_queue, 0);
I think, It should be:

Code: Select all

uart_driver_install(g_at_cmd_port, 1024 * 16, 1024 * 16, 100, &s_at_uart_queue, 0);

ESP32-WROVER-IE with ESP-AT

I see that WROVER-32 is not recomended (in factory_param_data.csv). What about WROVER-IE? Is it recommended? What module_name should be used while installation for WROVER-IE?
Is it better to use WROOM-32UE or WROVER-IE?
