I am working on a remote system connected to a computer I can remote into. I want to be able to send a command to thesytem via the serial port that will jump to the RST handler with flags for a download_boot. I would think there ought to be a way to do so. Probably a new task that kills off all it s...

I believe the solution is to use menuconfig and adjust the serial flasher config page. You have an option there to set flash size and to detect size when flashing. Saving the sdkconfig file is important.

A real (as in old school) embedded programmer would just do it manually, with truncating unsigned integer division and modulus arithmetic. One version for over 32 bits and one for 32 or less. Once the digit is identified, adding 30 to make it a character is trivial. Translating from signed to unsign...

I have have is probably a similar situation. It looks like normal state engine progression until: [0mD (23816) wpa: wpa_rx: new eapol=0x3ffd4fc4 [0mD (23820) wpa: WPA: f0:08:d1:6b:36:fc WPA_PTK entering state PTKINITDONE [0mD (23827) system_event: SYSTEM_EVENT_AP_STACONNECTED, mac:f0:08:d1:6b:36:fc,...

It should be bytes 6..11 in the datagram.
I suggest you get wireshark and capture some of your actual packets to ensure they are being built correctly.

It depends on what you planning to do with the data. Also on who the master is. If the ADC is master then all the ESM32 has to do is respond to interrupts, copy the data, and send it out on WiFi. That is likely doable with a single processor. If you plan to do any data processing, you will need to s...

I think there is likely a problem with getting such a file all at once. You would need to have something like DMA compatable RAM to drop the entire file into and I do not think any of the ESPs have enough of that that today. If you send it in small blocks with TFTP or some more robust protocol, you ...

I would like to see the real time clock able to survive losing VDD but keeping vdd_rtc. This would allow knowing the time when primary power was restored. I do not expect that the internal oscillator would be keeping perfect time, but it would provide some idea of the amount of down time for logging...

The other issue is that often people forget that they have to have allocated the space for a received buffer, not just a pointer to it. If you say char * MyPtr = malloc(128); that sort of limits you to the number of characters you can receive and is a perfectly valid way to get there. Right up to ch...

I am a wee bit confused by your mention of stop bits. If you are running with no stop bits (N-8-0) and you are seeing them, as the last active bit in a 10 bit pattern, then the other side seems to be cheating. If you are seeing your end of frame marker without a complete frame, that often implies a ...
