Module: EG800K-EU
Current firmware: EG800KEUCCR07A06M02_01.001.01.001
Hello
We need PPP over the physical main UART for an MCU host.
AT+CGDATA=? returns +CGDATA: (“PPP”).
ATD99**1# returns CONNECT.
However, after CONNECT the UART outputs no PPP LCP frames; host receives 0 bytes.
AT+CGDATA=“PPP”,1 returns CME ERROR.
AT+IFC=0,0, AT&D0, AT+IPR=115200, AT&W tested.
USB net modes 1/3 tested.
No RTS/CTS available.
Question:
Is PPP over main UART supported on this firmware?
If not, which AT-standard firmware build enables PPP over UART?
Thank you for your help !
best regards
I suggest you use the USB ECM or RNDIS protocol. PPP is more traditional.
AT+QCFG=“usbnet” // Configure the Network Card Type Interface
AT+QNETDEVCTL // Connect USB Netcard to Network
Unfortunately our host is an ESP32 MCU connected only through the physical UART.
It has no USB host interface, so USB ECM/RNDIS is not usable in this design.
Could you please confirm explicitly whether PPP over the physical main UART is supported on EG800K-EU firmware EG800KEUCCR07A06M02_01.001.01.001?
If it is supported, which command sequence binds PPP data mode to the main UART after CONNECT?
If it is not supported on this firmware, is there an AT-standard firmware build for EG800K-EU that enables PPP over UART?
PS : Your PPP Application Note V1.7 lists the EG800K Series as PPP‑capable over the main UART. Does the EG800K‑EU specifically support PPP, and if so, which firmware build enables it? Our current CCR07A06/A09 does not (usbnet rejects mode 0, and ATD*99# returns CONNECT but produces no LCP frames), which matches your note that PPP availability depends on flash size.
