You must upgrade. No question, none. The overflow issue has been there since the original driver. Understandably as the hardware API was not clear. Now IDF have moved on & fixeds lots. Invite mongoose to step up. IMHO overflow lock out is a school boy issue & unacceptable in a commercial offer. If ...

You must upgrade. No question, none. Even if using latest IDF then look at my posts & check that you have the ESP CAN silicon driver patches included. You're original driver is very much broke, that's not a criticism, the hardware was not documented & more power to the coder for getting CAN off the ...

Dear ESP, The ESP-IDF git branching model seems to allow convenient & semi automatic version number generation along with support for developing multiple versions. I see the overview but details like when you tag, how you branch/manage/merge a change which applies to multiple versions escape me. Wou...

Seems that you are not sending anything to the service!

You call vprintf() which sends to stdout.
Instead vsnprintf() and then send the string to both stdout and your network device.

CAN not working after a soft reset is a driver issue rather than the controller hardware. It is the driver's responsibility to clean initialise, so latest driver is a good idea. But yes, there are mechanism is the original ESP CAN driver which could explain. The most obvious mechanism would be overf...

Double stacks. Reboot after upload. You have done a firmware upgrade so reboot is legit even desirable e.g. prove your software works after boot and after upload (which is why most just reboot). There may be some underlying issue with your firmware that is further 'tempted' by the upload. Double sta...

Sprite is right. It depends. Its all good until you run out of RAM or hit latency issues. I use IDF/C++ because I can & I can because I have moderate volumes, moderate complexity, moderate throughput & so I can use ESP (with C++). Some use C/Asm & M2 etc because they must - they have high(er) volume...

Hey, Not sure about Ardunio but DMA under IDF adds a 20uS+ (ish) hit. A key point is the construction of the SPI transaction. IDF you can create this 'command' on the fly or you can create a command and then reuse. The performance difference is very important as frequency increaces... I am not sure ...

Hi, Left field: Why do you think that you need such tight DTR/DSR? They are really old school signals for back in the day 8080 etc limited processing equipment & perhaps without hardware 8251 support. I have not needed either since the 80's. The ESP should always be DTR (and I would bet large that a...

Idle scrolling but: int length = uart_read_bytes(uart_num, &rxbuf, rx_fifo_len, 100); Looks weird. Why would you offer a pointer to a pointer when you just want the client library to return data? This is an idle post so if the documentatiobn says other then shoot me down. Just seemed a very strange ...
