I am trying to implement the PPPoS from picotcp on HL6.
I have code working perfectly on SL6087 that works like:
ATZ
OK
ATE0
OK
AT+CREG=1
OK
AT+CGREG=1
OK
AT+CGDCONT=1,“IP”,“internet.proximus.be”,
OK
AT+CGATT=1
OK
ATD99**1#
CONNECT 38400
PPP: Modem connected to peer.

PAP: Received Authentication OK!
PPP: Authenticated.

Assigned ipv4 46.179.146.96 to device ppp0
setsockopt: Nagle algorithm disabled.
Launching PicoTCP echo server
When I try the exact same code, with exactly the same SIM card, on HL6 the negotation never gets passed LCP. And I just get:
Sending LCP CONF REQ
Received LCP CONF REJ
Sending LCP CONF REQ
Received LCP CONF REJ
What might be different on HL6 so that this doesn’t work on the HL6 modules?
