considering you have only 250 bytes, using JSON in ESPNow is VERY inefficient as you are sending not only values but also the keys and very often key length is longer than value (plus colon, quotation marks etc.)
@viper9x 4 місяці тому
Great video showing how easy it is to send data in JSON format, which is good when we might be returning different data at varying times, but that 250 byte limit makes JSON largely unsuitable for anything more than a few sensors at a time. For the particular use case you have demonstrated (sending 2 floats), since the size / format of your data is known at build time, you would be better sending that data as a C Struct. A struct of 2 floats would consume only 8 out of your 250 bytes. In JSON format you are using more than this just on key names, brackets and whitespace alone and your two floats are being sent as strings using significantly more space than they would need to be sent in binary format.

Great video .. I have doubt, that I am working on something with esp8266 board to send real time data to blynk. But for that controller I need a standalone power supply which I expect to run for months ( like batteries / mini solar panel ) .. but I can't find any useful resources for that in internet .. can you suggest your thoughts on that

Just because you can, doesn't mean you should. It is good for learning but we should know the real life application / use case of such projects.

oh please: I have reprogrammed all my environmental sensors that were working on WiFi (talking to my router) into ESPnow devices. I added 2 ESPNow2MQTT gateways and I have totally different (better) project now at home. Why? 1- WiFi sensor before it gets connected to router takes at least 600ms, usually around 1s (fixed IP, fixed channel). Add to that time to gather the data from sensors and you are at 1.5s at least 2- the same sensor on ESPNow takes around 20ms to get connected and to send data over ESPnow. So my sensors now are ready to go to sleep after around 200ms. 3- Having 2 ESPNow2MQTT gateways at home I am less dependent on where the router is and where the sensors are. Conclusion: battery life and coverage. Now my sensors are ready to stay on battery for around 1 year (still testing it but let it be even 8 months - it would be around 8 times longer than when they were on WiFi). But again: DON'T USE JSON over ESPnow - you are wasting your bytes and you have only 250 of them in ESPnow.

Can you tell me why JSON communication is better than normal? is the transfer speed more? is the dataload less? requires less power? why?
@CerebralDad Рік тому
Can this be used to send a base64 image through json?
@YigalBZ Рік тому
What is the added value of using JSON? Using esp-now with the standard way gets the same thing with much less effort. Also: I think STRING is a bad method to use.

Dear when I am compiling for receiver, I am getting this error "Compilation error: invalid conversion from 'void (*)(const uint8_t*, const uint8_t*, int)' {aka 'void (*)(const unsigned char*, const unsigned char*, int)'} to 'esp_now_recv_cb_t' {aka 'void (*)(const esp_now_recv_info*, const unsigned char*, int)'} [-fpermissive]"

Have you made any project where one esp will be connected to internet and other communicating without internet like their own hotspot or esp now. So that if I go the browser and ask ESP1 to turn on the light of ESP3 it can do that ?
@techiesms 2 роки тому
Yes The next project is exactly the same

How fast is the communication speed? Is it fast enough to use it as a transmitter and receiver for a quadcopter?

Hi sir Can we transfer audio and video from one esp32 to another esp 32 through esp now protocol
@thenextproblem8001 Рік тому
Yes you can. ThatProject channel and atomic14 channel made so many videos
@martins.-pach3979 Рік тому
Sizeof() is an incorrect way to calculate the size of a pointer, this can lead to incomplete data therefore an error. Use: measureJson(doc)
@osvaldotcf Рік тому
Data for espnow < 250 bytes Json doc = 1k This is correct ?
