It's not possible to set on_read_cb from C API yet.

As a workaround you can check what's done in the mdoem-console example. It implements a generic command that takes a pattern matching string as an argument, so you can wait for a ready signal, or some specific string (such as +CLIP: in your case), e.g.

esp> cmd -n "" -t 50000 -p "SIM"
I (442984) modem_console: Sending command  with timeout 50000
I (459154) modem_console: 
RDY

+CME ERROR: SIM not inserted

esp>

esp-protocols/components/esp_modem/examples/modem_console/main/modem_console_main.cpp

Lines 228 to 238 in b8d1e58

CHECK_ERR(dce->command(cmd, [&](uint8_t *data, size_t len) {
std::string response((char *) data, len);
ESP_LOGI(TAG, "%s", response.c_str());
if (pattern.empty() || response.find(pattern) != std::string::npos) {
return command_result::OK;
}
if (response.find(pattern) != std::string::npos) {
return command_result::OK;
}
return command_result::TIMEOUT;
}, timeout),);

Is it better for you to be able to set the actual callback and check the results manually? Or alternatively extend the existing at_command() to allow for the pattern matching in replies?
The first option is more universal, but wouldn't support sending any other AT commands while it's active (Unless you use one more virtual terminal)
