Re: Will esp8266 SDK support channel state information (CSI) in the future?

It would definitely be interesting to get the radio tap header information (including rss) for some security applications.

Re: How L108 CPU communicates with WIfi CPU in ESP-WROOM-02?

Anyone? Is it via SPI or is it a peripheral connected via AHB? Are there registers which can be accessed, is there a DMA channel or interrupt whatsoever provided just for WiFi? Is there a possibility to get the entire packet information (including radio tap header)?

Re: New FEATURES gathering

Access to entire packets (including radio tap header containing RSSI information added by NIC) would be nice.

Packet RSSI Value

Hello there from Germany. Is it possible to get the RSSI value from an received packet while the WiFi is in WIFI_STA mode without being in promiscuous mode? Can you tell me the register address/offset which can be read with "READ_PERI_REG()" which is mapped to the WiFi hardware specific re...

Re: ESP8266 RSSI of received packet

Hello there, We are coming from Ruhr-Universität-Bochum and we are doing research in the area of indoor localization systems. If we had the RSSI value on a per-packet basis, we believe we could enhance the precision and do other incredible stuff with the ESP8266. Without this crucial component (the ...

Re: ESP8266 RSSI of received packet

Hello again. Thank you very much for your fast answer. Currently, we are developing our prototype on your ESP8266 and we urgently need the RSSI value on a per-packet basis in WIFI_STA mode. My point is: I believe that the API does not allow to read the RSSI on a per-packet basis, but if you can read...

ESP8266 development difficulties

Hi there. Apparently, ESP8266 does not offer good efficiency characteristics. I have been scrambling everything to find out as much as possible, but the question still remains: Which registers are used to change the behavior of the integrated PLL or the main clock for the CPU? Which registers are us...

Re: ESP8266 RSSI of received packet

Hi.

It seems that a received packet is parsed in a JSON-Tree called _ctx. If this is true, how do I acces the element containing the RSSI?

Re: ESP8266 RSSI of received packet

Hi. This is the RSSI value for the last beacon frame. What I need, is the RSSI from the radio tap header which is added by the wifi hardware when a packed is received. In promiscuous mode, the RSSI can be found in the packet which is given as an argument to the wifi promiscuous callback function (st...
