Re: UART Communication problems at 921600

What I have noticed however is if I send 1400 bytes the uart_read_bytes returns a value in the range of 1390. If I send 600 bytes I get a len of approx 596. Hi, LukeSkyWire Have you enabled hardware flow control? At 1M baud, the CPU can read out the data in fifo in time. But At 2M baud-rate, the CP...

Re: UART Flow Control

Re: UART Flow Control

Please when answering questions remember that other people try to find solutions here. It is so annoying finding the questions in the forum but no real answer. I don't understand what the sw flow control does based on documentation. I also tried searching for examples of uart with DMA and always fin...

Re: VS Code - Size Analysis

I'm on windows 10, IDF 4.0, Extension version 0.2.1, vscode 1.45.0. This happens to everyone on different PCs with the same big project we are working on. Trying out different projects gives different results for the maximum DRAM and IRAM available, which makes no sense to me. I'm compiling for the ...

Re: Esp32-s2 and bg95 PPPoS over USB?

What do you mean by the class drivers for modems?
Is PPPoS not available yet over UART like for esp32?

we would like to conmect both uart and usb so that we can work on the usb when it becomes supported in the idf, but use the code we already had working with esp32 by using PPPoS over UART.

thanks

Esp32-s2 and bg95 PPPoS over USB?

can the USB 1.1 OTG on the esp32-s2 be used to communicate with a modem like bg95 instead of using UART to achieve higher speeds?
has anyone done something with the USB port yet?

we are considering changing one esp32 with the esp32-s2 for handling wifi and 4G communication.

thanks

Re: Cmake is not looking for components in EXTRA_COMPONENT_DIRS

Can someone from the esp team explain how we are supposed to achieve this?
Just following the docs I could not make it work and nvannote's way did not work with our project, so how is the official way to include components that are not in the project folder?

Re: What files to keep from a specific revision build, and how to flash

most of the times you'll have one yourproject.bin for your flash partition, you also need the partition-table.bin, bootloader.bin and sometimes ota_data_initial.bin if you are using OTA you can program with esptool.py esptool.py --chip esp32 -p ${config:idf.port} -b ${config:idf.baudRate} --before d...

Re: Cmake is not looking for components in EXTRA_COMPONENT_DIRS

set(EXTRA_COMPONENT_DIRS "../common/some_shared_component") I tried it this way, but get the same error. How should one link to the some_shared_component from inside the project components that REQUIRE it? The way I thought it would work and that I think would be the most usefull is if: 1. look for...
