Re: ESP-NOW

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.

build and run-time errors using psram

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...

Re: ccache error during building

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.

Ivo

Re: ccache error during building

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...

ccache error during building

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 ...

Re: esp-now channel setting when in wifi station mode.

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...

Re: esp-now channel setting when in wifi station mode.

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...

Re: esp-now channel setting when in wifi station mode.

As a matter of interest, what branch/commit of the repository are you using? I don't have experience with my esp-now network also connecting to an AP. Do you get a send error if you feed peer() with .channel set to anything other than 0 or the AP channel? If I have understood you correctly, it could...

esp-now channel setting when in wifi station mode.

I have an esp-now network operating with the wifi set to station mode. The wifi is only used for esp-now and doesn't connect to any access point. I am currently using the release/v4.1 branch of the repository (commit 328c659c) which includes fixes for channel checking in the peer() process. I note t...

Re: idf_tools.py error

Hi Rolland, Thanks for your fast reply! I have now got it working again, but only be removing python and reinstalling with esp-idf-tools-setup-2.2.exe. I'm currently on branch release/v4.0 git describe --tags -> v4.0-beta2-295-g20e6d46d4 It would have been nice to be able to fix things without a com...
