I followed the tutorial to add the xiao esp32 c6 which kind of worked. It showed the board in board manager but could not create a project using it.
Also…I attempted to use NimBLE library for bluetooth but this did not work either. I could not compile a blank sketch without missing file errors. Has this happened to anyone else? I really want to be able to use the c6 xiao units that come with the new mmwave radar kits but so far I’ve had to swap them out for and xiao S3 because the bluetooth portion is essential to my project.
This compiled and worked fine until I added the NimBLE library which resulted in the following errors…

It seems it cannot find syscfg anywhere. this doesnt happen when i use a xiao esp32s3. Any ideas would be welcome.thx
Hi there,
So I was able to build and upload the Example sketch for Server_multiconnect.ino
I created a new Project and pasted it into the main.cpp
I had to tweak the Platform.ini to the following to build and upload Successfully.
The Git for ESP32C6 is updated to 3.0.7 and ESP_IDF to v5.1
Builds and works like a champ. SO why NimBLE?
matter or zigbee?

Serial.println("Waiting a client connection to notify...");
}
void loop() {
// notify changed value
if (deviceConnected) {
pCharacteristic->setValue((uint8_t *)&value, 4);
pCharacteristic->notify();
value++;
delay(10); // bluetooth stack will go into congestion, if too many packets are sent, in 6 hours test i was able to go as low as 3ms
}
// disconnecting
if (!deviceConnected && oldDeviceConnected) {
delay(500); // give the bluetooth stack the chance to get things ready
pServer->startAdvertising(); // restart advertising
Serial.println("start advertising");
oldDeviceConnected = deviceConnected;
}
// connecting
if (deviceConnected && !oldDeviceConnected) {
// do stuff here on connecting
oldDeviceConnected = deviceConnected;
}
}

Connects with NRF-Connect for desktop BLE and Nordic dongle and on the Nrf_connect for Android AOK a two to one connection.
I attempted to repeat the XIAO ESP32C6 with platformIO wiki using the platform.ini code you posted above. I was able to repeat the wiki without any issues but when I try to create a new project with the newly added seeed studio xiao esp32c6 board I get the following error…
`PIO Core Call Error: "The following files/directories have been created in C:\Users\elect\Documents\PlatformIO\Projects\c6 test oct28\r\ninclude - Put project header files here\r\nlib - Put project specific (private) libraries here\r\nsrc - Put project source files here\r\nplatformio.ini - Project Configuration File\r\nResolving seeed_xiao_esp32c6 dependencies…\r\n\n\nUnknownBoard: Unknown board ID ‘seeed_xiao_esp32c6’
It seems the board creation wiki does not work for me. Any ideas?
