I have a question regarding the C5 Wifi band switching. Does it automatically connect to the 5G or 2.4G of the AP (the AP has dual band enable on the same SSID) and switch to best band when available especially when roaming ?. Thank you. |
Hi @alberk8 , when the AP uses the same SSID and password for both 2.4G and 5G, the STA (station) will automatically choose the best band to connect to. Considering that the 5G signal attenuates more than 2.4G at the same distance, we have added a configuration option, rssi_5g_adjustment, to help decide whether to connect to the 5G or 2.4G band. |
and how to get that sample? :P |

I already have last week. |
Can Thread Border Router be operated solely on C5 without any additional SoC? Coexistence of 802.15.4 and WiFi is already implemented... |
@dmartauz There is only one RF path in ESP32-C5, which means Wi-Fi and Thread can't receive simultaneously, it has a significant impact on performance. Hence the two SoCs solution is recommended: ESP Thread BR |
@chshu I am aware of the dual-SoC approach, however it introduces complexity to OTA remote firmware update of RCP, which could be avoided if only one MCU was involved. Can coexistence limitations of WiFi and 802.15.4 on C5 be described in details? I found this resource for coexistence limitations of C6, however WiFi vs 802.15.4 limitation table is not included: https://docs.espressif.com/projects/esp-idf/en/latest/esp32c6/api-guides/coexist.html |
The ESP Thread Border Router SDK supports the RCP update feature. It automatically flashes the RCP firmware to the RCP SoC during the first boot, making the process seamless for the application. A single OTA update to the host SoC is sufficient. As a Thread Border Router, the 802.15.4 interface must continuously receive data. However, since there is only one RF path, whenever Wi-Fi uses the radio for transmission or receiving, the 802.15.4 interface cannot receive, potentially leading to packet loss. The higher the traffic on Wi-Fi, the greater the packet loss rate on 802.15.4. The ot_br example can run on a single Wi-Fi + 802.15.4 SoC (ESP32-C6, ESP32-C5). The BR functionality works, but it is not recommended for production use due to the high packet loss rate and poor performance. Please file an issue here: https://github.com/espressif/esp-thread-br/issues, if you have further questions. |
Does "802.11ax: 20MHz-only non-AP mode" mean the C5 cannot work as softAP with 11ax? I received a pair of C5 sample devkits this week and am trying to get them to talk 11ax in a private 5G network, one as ap and one as sta, and they always negotiate 11an. Is there a way to enforce 11ax in ap/sta or otherwise? TIA! |
@h-milz C5 can work as softAP with 11ax. If do not set wifi protocol when config softap, the softap will start with 11N protocol. You can use API esp_wifi_set_protocol() or esp_wifi_set_protocols() in esp_wifi.h to set the softap protocol to 11AX. |
@QingzhaoYin thank you for picking up. My answer is too long for this thread and I don't want to pollute it. I created feature request #15178. |
Can I use ESP-NOW with 5Ghz? |
@weoiss1998 If you have one of the ESP32-C5 samples, then yes. I was able to see and connect to my 5GHz networks. |
Could you provide an approximate mass production schedule for ESP32-C5? I have a product that urgently requires a 5G WiFi chip. |
@weoiss1998 Yes, ESP-NOW is supported on both 2Ghz band and 5Ghz |
@Jddl Please feel free to contact us. Our customer support team will provide you with the latest schedule and resource updates. Thank you! |
@Espressif-yangxi I tried emailing [email protected] but was told to go to the forums because I was emailing through a Gmail account and not a business account even though I am not a business and need it for a personal project as I am making software for the esp32 series that gives flipper zeros wifi (flipperHTTP) and need to make support for 5ghz. I was told to go to the forums, but there was no information there, and I was told to contact [email protected]. How can I get a sample? Please help me. If anyone has any extras I would be willing to buy one off of you. |
@DogAwesome21 Sorry for any confusion caused by our previous responses. Here’s the clarification to help resolve any misunderstanding: |
Hi guys, I have a question concerning 5G Channel and Country Code. I assume this will be ready in IDF 5.5, but may I ask if there will be something similar to 2.4 GHz international safe mode, allowing only channels that are safe in most if not all countries according to this list? My project should be usable worldwide, and I would like to avoid having to add any controls for a country setting. Thank you! |
@h-milz In the near future, we will support country codes related to 5G channels and there will be something similar to the 2.4 GHz international safe mode (country code "01"). For now, you can configure the supported 5G channels through the field
