Tip As of 2026, lpac is much easier to use. It replaces the use of AT commands with QMI (or MBIM). The instructions below are no longer relevant.

On a Quectel modem, a patch might be needed to reliably send AT commands to the modem. This patch comes from the fork lpac-quectel in the file drivers/at.c

We'll also reduce the size of transmissions to the modem to help the modem keep up.

Make the following changes before running make.

  1. Merge the changes in lpac-quectel's at.c into the upstream lpac's at.c. [TODO: provide a patch file or get it pushed upstream]

  2. Edit the file euicc/euicc.c to decrease the size of e10b_mss 

   ctx->es10x_mss = 60;

Hopefully, in the future these steps will not be necessary.
