ppp를 통해 SIM7000E를 설정하려고 합니다. SIM7000E는 마이크로 USB 케이블을 통해 비글본블랙에 연결됩니다. Beaglebone은 5.10.168-ti-r71 커널(Debian)을 사용합니다. SIM7000E 드라이버가 성공적으로 설치되었으며 ppp도 설치되었습니다.
나는 /etc/ppp/peers 디렉토리로 가서 파일 제공자를 복사하고 이름을 gprs로 지정했습니다. Gprs 파일은 다음과 같습니다:
# example configuration for a dialup connection authenticated with PAP or CHAP
#
# This is the default configuration used by pon(1) and poff(1).
# See the manual page pppd(8) for information on all the options.
# MUST CHANGE: replace myusername@realm with the PPP login name given to

# There should be a matching entry with the password in /etc/ppp/pap-secrets
# and/or /etc/ppp/chap-secrets.

# MUST CHANGE: replace ******** with the phone number of your provider.

원격 끝은 압축 요청을 완전히 거부합니다.

그 후에는 원격 끝이 완전히 응답하지 않습니다. 분명히 "압축"은 낯선 개념이므로 일단 언급되면 연결 협상을 계속할 수 없습니다.
한 줄 nodeflate에 하나씩 키워드를 추가하거나 두 가지 모두를 추가해 보세요 .nobsdcomp/etc/ppp/peers/gprs
또 다른 가능한 문제는 IPv6일 수 있습니다. 모바일 네트워크 공급자가 IPv6에 대한 절대적인 지원을 입증하지 않는 한 IPv6가 요청될 때 트리거되는 원격 측에 일부 버그가 있을 수 있다는 사실이 그리 놀랍지는 않습니다. .noipv6
또는 이동통신사에서 제공하는 경우IPv6 전용(개인적으로는 이런 일이 발생하는 것을 본 적이 없지만 IPv4 주소 부족이 더 심각한 일부 국가에서 발생할 수 있는 것으로 보입니다.) 다음을 추가해 볼 수 있습니다 noip. IPv6만 사용할 수 있는 경우 원격 끝은 모든 연결로 구성될 수 있습니다. IPv4 요청 시도가 완전히 거부되었습니다.
두 가지를 동시에 추가하지 마십시오. noipv6그렇지 않으면 noip연결이 거의 쓸모가 없게 됩니다. 둘 중 하나만 추가하면 됩니다.
그러나 SIM7000E가 네트워크에 전혀 등록되지 않은 경우 이것이 문제의 근본 원인일 수 있습니다.
/etc/chatscript/gprs명령에 지정된 APN 이름을 얻기 위해 이 옵션을 사용할 것으로 예상했지만 현재 이를 제공하지 않았습니다. 예를 들어 사용해야 하는 APN 이름(공급업체에 문의)이 다음과 같은 경우 다음 줄을 변경합니다.chat-Tinternet/etc/ppp/peers/gprs
