Apologies folks - ignore the above, I made a very basic mistake.

I would like some help with a uart problem please. I have an esp32 that needs to talk with two other esp32's with low latency. I have chosen to use UART_NUM_1 & UART_NUM_2 for this purpose. I am running them at 16 Mbaud, which they seem to cope with OK. I am using uart_write_bytes() with a tx ringbu...

I am working on branch release/4.1. Everything was working fine on commit 84b51781c (23/5/2020) but when I tried commit bd72a9ab (3/8/2020) I get compiler errors. The compiler has been updated from 2019r2 to 2020r2. The tool paths are correct but the compiler can't find some header files. For exampl...

Hi Mr Techtron,

I believe if you have only ESPNOW, you can have up to 10 encrypted pairs. If you are running both ESPNOW and have a wifi soft-AP, then you can only have 6 encrypted pairs.

I have an espnow application running satisfactorily, to which I am now adding bluedroid - spp. In order to minimise IRAM usage, I have disabled both CONFIG_ESP32_WIFI_IRAM_OPT and CONFIG_ESP32_WIFI_RX_IRAM_OPT. All of my queues use heap allocated in psram. The psram spi clock is set at 80MHz and the...

Hi Angus,

I believe you hit the nail on the head. Thanks very much for taking the time to reply.
The registry was already set for long path lengths, but the "idf.py -B D:\proj_build build" worked correctly.

Your help is very much appreciated.

I didn't notice, but earlier in the build output there was a failure: Generated D:/Repositories/Project-Folder/Espressif/esp-idf/New_Development/esp-now/build/bootloader/bootloader.bin [737/903] Building C object esp-idf/libsodium/CMakeFiles/_...lsa208sha256/nosse/pwhash_scryptsalsa208sha256_nosse.c...

Hi, Apologies if this has already been addressed - I couldn't find a solution. I'm currently trying to build an application using the release/v4.1 branch (commit 5dbabae). I re-cloned the esp-idf directory and ran install.bat (windows 10 shell), followed by export.bat. The build seems to work until ...

The issue report is hopeful: "We are trying to modify this function to let it can set the channel as long as the wifi initialized, thus you can set the channel in STA mode. But we will still don't support setting channel when the STA has connected to an AP, or when STA is scanning, or STA is connect...

As I understand things, setting . channel in peer() has no effect on setting the radio channel - implied in the documentation. It must however be set to 0 or the same as the radio channel or you get a send error. Hence my original question, how do you set the radio channel when it is set up as a sta...
