Re: 需要ESP32做AP,可以连接6个sta, 同时在AP测建立tcp server,要求可以连接6个client。

可以调用esp_wifi_set_config(AP, config)设置AP的最大可连接数。
tcp server我这边测试是可以连接多个client的,没有发现限制为2个。

Re: ESP-NOW specifics [WIFI-2245]

In STA+AP mode, the STA and AP are in the same mode. If you set softAP to channel 1, then STA connects to an AP on channel 6, the softAP will change to channel 6.

Re: ESP-NOW specifics [WIFI-2245]

yes, you are right, the ESP-NOW channel is directly tied to the WiFi channel. So we don't suggest you use ESP-NOW and WiFi connection at the same time. If you want to send ESP-NOW data to all peers, you can set the peer_mac to NULL in `esp_now_send()`. Refering https://docs.espressif.com/projects/es...

Re: esp-now and number of nodes [WIFI-2126]

We set the number of nodes because of resource constraints, especially for the encrypted node, we need to save the key.

Re: esp-now and number of nodes [WIFI-2126]

hi sajjadakhter, 1. Do i have to add node to my peer list to send message? can i just send message without adding to peer list. Can i reieve message from node that's not in my peer list? Yes, you have to add node to the peer list, otherwise, `esp_now_send()` will return error, but you can receive me...

Re: Send analog values using espnow

Hi ShadowJ14,
In your last post, do you mean you can send and recv analog values successfully?

Hi knightridar,
Have you tried ShadowJ14's method ? Do you still have the problem?
