Hi everyone,

I would like to bulk-write json data to Thingspeak using AT commands (I'm using SIM7600 module). As I want to send a large amount of data at the same time, the json buffer is not enough. So I'm posting from a file. However I always get a 401 error code.

Does someone know why I get this error ?

The whole commands and results are reported below.

Thank you in advance

The bulk endpoint requires a somewhat complex syntax. Check out the bulk JSON update page here. You aren't providing all the correct information, for example AIP key, etc.
