Pairing with QR Code does not work reliably

Hello,

i am trying to get every feature working, including the QR Code assisted paring.

I did specify: homekit_server_config_t accessory_config = { .accessories = accessories, .password = "915-71-923", .setupId = "WMUT", //optional }; SetupID and password. These were used for generating the QR code with the script from maximkulkin. However pairing with this code does not seem to work reliably. This is a failed try: `>>> [ 47439] HomeKit: Starting server

A iPhone was used to connect. It did show "device can not be added“ error. Sometimes the pairing works like it should, sometimes if fails with this error. Sometimes it also fails with a "unknown error: 2025" displayed on the iPhone but i don't have a log from this. I did already follow your example of running only arduino_homekit_loop() while not paired.

Did i do something wrong or is the esp8266 to slow?

Make sure that CPU frequency is set to 160Mhz

I already used QR code pairing successfully. Yet, when I had problem, I did that to solve it: "erase the full flash or call homekit_storage_reset() in setup() to remove the previous HomeKit pairing storage and enable the pairing with the new accessory of this new HomeKit example." Boot the ESP. After that, reflash the ESP without homekit_storage_reset() and then try to pair.
