Json for wifi kit 8 is broken

This link: https://docs.heltec.cn/download/package_heltec_esp8266_index.json
contains an error in the json. Line 44 has two strange characters instead of a , . Or maybe it should be a newline, but it will not load in the IDE.
Arduino15\package_heltec_esp8266_index.json, parsing error occured:
com.fasterxml.jackson.databind.JsonMappingException: Unexpected character (‘£’ (code 163)): was expecting comma to separate Array entries
at [Source: (FileInputStream); line: 44, column: 11]

I have the same problem. On Arduino IDE 1.8.10 (the last) when search for new board I have the following message:

com.fasterxml.jackson.databind.JsonMappingException: Unexpected character (‘£’ (code 163)): was expecting comma to separate Array entries

I’m having the same issue. was a solution ever found?

Hi, there, very sorry about that problem, we are trying to fix that problem, but the network really so terrible here, we can’t download many packages for test.

Can you please try this url?
https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/releases/download/0.0.4/package_heltec_esp8266_index.json

We are still finding a better way to solve the network for GitHub…

Still not working for me: installation ends correctly, but I cannot see the “WIFI_Kit_8” entry in the Board list. Moreover, the following errors are displayed by the environment:

I get the same error as well.

I solved by following the guide for installing from GitHub, but when I try to build, the following error is shown:

Actually there’s no python3 directory, but why is it searching it there? Does anyone know?

No more people struggling to install the WiFi kit 8 in Arduino IDE?

It’s hard to believe that Heltec isn’t putting all the efforts on solving this issue. I and many others will be forced to change platform…

Revision 0.0.4 is broken, so i just use old release version from – https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/releases/ , unfortunately i have found only 0.0.1 version. This is one year old revision
https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/releases/download/0.0.1/package_heltec_esp8266_index.json
but is works.

similar problems here. tried installing v0.0.4 and also v0.0.1 via this link:
https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/releases/download/0.0.4/package_heltec_esp8266_index.json

unfortunately the wifi kit 8 is not showing up in boards list, only some heltec ESP32 Boards seem to be installed. Same for both versions. Anyone can help?

Hi there

Very sorry about this problem. Because of the network problems in China mainland, many dependent files download very slowly or disconnected … This caused the previous test to be very difficult. Finally, it had been fixed this afternoon.

Please try this json url:
https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/releases/download/0.0.4/package_heltec_esp8266_index.json

works now for me. Thx for fixing!

HI, Sorry, but the link seems like not working again.

Hi, I loaded the 8266 file and it shows in the manager, but if you hit the “more info” button it takes you to the esp32 page in github. Could it be trying to load the 32 file but calling it the 8266, any comments?

Open Arduino IDE, and click File -> Peferences -> Settings
Input old esp8266 board manager URL
(https://github.com/Heltec-Aaron-Lee/WiFi_Kit_series/releases/download/0.0.1/package_heltec_esp8266_index.json)
Click Tools -> Board: -> Boards Manager... , search Heltec in the new pop-up dialog, then click install
is works.

Yes, it is working great now. Thanks.

Hi, i have the same problem. The wifi kit 8 isn’t showing in board list in Arduino 1.8.12.
I have this message
Anyone can help? Thanks
