USB CDC 4G MODEM - SPEED ISSUE (AEGHB-412)

Open lovepreethitech opened this issue 1 year ago • 4 comments

Hi @leeebo

I am using ESP32S3-WROOM1-N16R8 with my modem, I am facing speed issues. Ping time is in thousands of seconds and taking too much time to open to webpages even.

MODEM ENDPOINTS - 0x85 0x04

Please suggest what could i improve to increase speed. I Checked my modem in dialup mode with directly connected to PC giving good speed.

Attached Menuconfig - sdkconfig.zip

@lovepreethitech Hi, which 4G model are you using?

@leeebo I m using Neoway N58 module - https://www.neoway.com/products/wireless-communication/823.html

Also i have tried the same on Quectel EC200u but similar speeds.

previously i was usign ESP32S2 without PSRAM but getting slows speeds then shifted to ESP32S3 N16R8 but same results.

Please suggest if there are any configurations i can tweak.
