Re: ESP-NOW

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.

Re: ESP-NOW

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.

Re: ESP-NOW

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

ESP-NOW

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.

Re: How do I use esp32 as an external RAM for other microcontroller?

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...

Re: How do I use esp32 as an external RAM for other microcontroller?

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?

How do I use esp32 as an external RAM for other microcontroller?

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.
