[lwip-users] lwip on pico_w

[Edward Vidal]

Hello All

My code is found at https://github.com/develone/pico_w-mqtt.git in the dev branch.

I have tried to document my build found at https://github.com/develone/pico_w-mqtt/blob/dev/doc/pico_w-debug.pdf
I use RPi4 to build 6 remotes (remote1, remote2, remote3, remote4, remote5 and remote6).  I do everything the command line.
I see others using Visual Studio or Eclipse.

I use openocd to program the pico_w

This is the output of tcp_debug task (cli1, cli2, cli3, cli4, cli5, and cli6)

../pi_tcp_tests/cli1

Christoph M. Wintersteiger form lwip-users suggested the following

cyw43_arch_lwip_begin();

err_t r = mqtt_publish(client, topic, payload, payload_length, qos, retain, cb, arg);

cyw43_arch_lwip_end();

I added 12 pairs to my https://github.com/develone/pico_w-mqtt/blob/dev/pico_w/wifi/freertos/iperf/picow_freertos_iperf.c

https://github.com/develone/pico_w-mqtt/commit/9ff1e19b1457e138d317f67c23a2832cd3b7a853

mqtt.c prototypes defines 39 functions

https://github.com/develone/pico_w-mqtt/blob/dev/doc/mqtt-prototypes.txt

Since these are not called I did not add the cyw43_arch_lwip_begin();/cyw43_arch_lwip_end();

Currently testing 3 pico_w.

Thanks
