[lwip-users] lwip ppp using gprs modem

[chrysn]

hello lwip users,

i'd like to modify a running lwip application to use a cell radio
connection (gprs). occasional gprs themed posts on the list imply that
it is repeatedly done, yet i failed to find particular examples with
code.

* are there particular chips known to work well? i'm currently having
  closer looks at SIM340DZ (in use in [1], but not available at some
  common vendors) and huawei MG323-B (just didn't find its AT command
  description yet).

* is there a proper library that can deal with all the AT command stuff,
  and preferably hook directly into lwip's ppp handler?

  what do others who use gprs with lwip use? there must be more than a
  bunch of custom-written AT expect-style loops...

best regards
chrysn
