能否实现PPP拨号功能+构建HTTP服务器?

Postby lcode- » Tue Apr 26, 2022 8:52 am

1、我已经通过修改usb_cdc_4g_module demo实现PPP拨号上网,但是加上HTTP服务器后,HTTP服务器会访问不了,PPP拨号上网也会异常。 :shock:
2、单独构建HTTP服务器,不使用PPP拨号上网,HTTP服务器没问题
3、日志,PPP+HTTP功能,在访问HTTP服务器会返回错误:esp-netif_lwip-ppp: pppos_input_tcpip failed with -1

Code: Select all

-1 表示 ERR_MEM,内存不足,建议你打印下内存看看。
