Oh, I didn't notice that. Thank you WiFive for the redirection.

Can anyone say why there is no code for CAN driver in the latest esp-idf version (v4.3)?

I'm using ESPNOW in WIFI_MODE_STA mode but can only add 6 peers.
In esp_now.h there is
#define ESP_NOW_MAX_ENCRYPT_PEER_NUM 6 /*!< Maximum number of ESPNOW encrypted peers */

I set it at 10 but I've got no success.

After some digging, I manage to get the RSSI value by enabling the promiscuous mode and implement filtering based on the frame control field of the mac header.

Is there any way to get the rssi value using esp-now protocol?

In the esp-now user guide, it is mentioned that one can connect up to 10 encrypted pairs, but in esp_now.h "ESP_NOW_MAX_ENCRYPT_PEER_NUM" is defined as 6. Can someone please explain this, since I can't find enough documentation about ESP-NOW.

Thank your for your concern. I think I've to do some more digging myself then.

Yes, you're absolutely right but I want to use the wifi/ethernet/BlueTooth capability of esp32 too as a communication interface. If I could use it as an external RAM, it would be an icing on the cake. I just want to know if this could be achieved and to what extent. With this, I can extend the capab...

Thank you @ESP_Sprite for your response, this is just a general question as a hobby project if this could be achieved. I'm thinking of using SPI if that is not possible could it be possible with FSMC of stm32f407?

This might sounds quite stupid but I was wondering if esp32 can be used as an external RAM for other micro-controllers? Please, can someone shed some light on this topic, is there any way that I could achieve this? Thank you.
