Hello,
I’m using Quectel M66 to send post data with a custom header. I was wondering why it takes approx 6-8 seconds to get a CONNECT response from the GSM module. Reference:
Between QHTTPPOST commands and CONNECT responses, the module waits for far too long as opposed to when I make the same post request on PostmanAPI or any other platform it’s way quicker (400ms delay or even less). Both requests are sent to the same url. How do I speed this up? If it’s not possible, can BC65 perform any faster? What causes the huge response delay?
For the record, I’ve tried doing the same request to another url (webhookapi) and the CONNECT response was delayed about 6 seconds while using M66.
Custom post content is as follows:
Host: urlhostname
Content-Type: application/json
Accept-Encoding: gzip, deflate, br
Connection: keep-alive
Content-Length: arbitrary length
{arbitrary data within the given length}
Given the circumstances, I’ve figured out that this is the maximum speed I can achieve with the module.
The slow speed is determined by the GSM network mode，You can choose the faster cat1 or CAT4 modules
