esp8266 add device failed. Write value too large [json.c] #79

HomeKit: [Client 1] Verification successful, secure session established HomeKit: [Client 1] Get Accessories !!! HomeKit: Write value too large HomeKit: [Client 1] Closing client connection

I try to add led device using demo code led_strip and failed logouting info like adove.

Did you change anything? I do not see anything that could cause it. This issue is when you try to generate a JSON with a single value larger than the whole JSON buffer. JSON buffer for get accessories is 1024 bytes. I feel like you have a dangling/uninitialized string pointer or non-terminated string.

Hello, I got some troubles!

because someone say look at: https://github.com/maximkulkin/esp-homekit/issues/24:

I change [json.c] as:

void json_float(json_stream *json, float x) {
   ...
    void _do_write() {
        json_write(json, "%1.15g", x); 
    }
   ...
}

to 

void json_float(json_stream *json, float x) {
   ...
    void _do_write() {
        json_write(json, "%ld", x); 
    }
   ...
}

doesn't work for me !!!

Compile warnings 

warning: initialized field overwritten [-Woverride-init]
     HOMEKIT_ACCESSORY(.id = 1, .category = homekit_accessory_category_lightbulb, .services = (homekit_service_t*[]) {
     ^
warning: (near initialization for '(anonymous).category') [-Woverride-init]

Here my example code:

void json_float(json_stream *json, float x) {
   ...
    void _do_write() {
        json_write(json, "%ld", x); 
    }

Hello again !

If I don't change the code[json.c] 

void json_float(json_stream *json, float x) {
   ...
    void _do_write() {
        json_write(json, "%1.15g", x);

void json_float(json_stream *json, float x) {
   ...
    void _do_write() {

I don't know how to deal with it now ！！！

If you get lost, you can fallback to using ESP-OPEN-RTOS instead which is the official supported SDK for esp-homekit.

Thanks to @maximkulkin, but we have to use ESP8266_RTOS_SDK to do something，is it because they are different, you know what the reason might be ?

The error !!! HomeKit: Write value too large occur to is because [json.c] do not support float value in esp8266 ? Can I replace json_write(json, "%1.15g", x); with json_write(json, "%ld", x); ?
