Bug report :: BC660K-GL HTTPS - Large payload causes reboot

Technical Subjects Software Internet Protocol
1

When the HTTP payload buffer exceeds ~6KB for HTTPS requests the module reboots. Normal HTTP requests can safely handle 7KB of payload without error.

Module: Quectel_BC660K-GL
Revision: BC660KGLAAR01A05_01.001.01.001

The first request seems fine. The moment I try to make the exact same request again the module responds with “OK” and then restarts itself without providing any error response.
