ESPnow ESP8266 <==> ESPnow ESP32 pair without using AP possible?

On ESP32 I can pair devices without using AP mode for the detection by using broadcast messages over ESPnow. How can I achieve the same on ESP8266? On an ESP32 I do initialize ESPnow with tcpip_adapter_init(); esp_event_loop_init(espNowEvtHandler, NULL); wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEF...

Re: ESP8266 - GOOGLE CLOUD MESSAGING WITHOUT EXTERNAL SERVER

wuyunzhou,
Correct, that is how it works. However I didn't use the "priority" and "time_to_live' keys.

ESP8266 - GOOGLE CLOUD MESSAGING WITHOUT EXTERNAL SERVER

I was looking into a solution to send push notifications from an ESP8266 module to an Android application. I know that this is possible with the Google Cloud Messaging service. But what I found on the internet is using an external webserver, able to run PHP (or Python) scripts and using a MySQL serv...

Re: Cannot recover from Fatal exception (0): problem during boot

Would you like to ship your dead module to us? we have very strict RMA policies and we would like to conduct a postmortem on this. There are many possibilities and for this case, the manufacturing process has been rather convoluted from a module house to Adafruit to you. it may be hard for us to pi...

Re: Cannot recover from Fatal exception (0): problem during boot

I think it's possible that the flash device might have failed. the other possibility is with the regulator. yes, while it's possible that ESP8266 might have failed, it's extremely unlikely. If it has failed, then probably it is due to very high voltage ESD on the VDD_RTC pin, or VDD33 pin. it's bes...

Re: Cannot recover from Fatal exception (0): problem during boot

Hi, Did you use 5V power supply to connect to ESP8266 directly ? Could you help us debug the hardware of your module following below steps : 1. Measure the voltage of ESP8266's pin VDD. 2. Use hot air gun to remove the wifi Chip from the PCB board and measure the resisitence of each pin to the grou...

Sorry that it seems your module is broken. Please try it with another module..


I was afraid it is broken. What exactly is the "EFUSE" doing? Any chance to repair the board by e.g. replacing the flash chip?
