Unable to build esp-at for Classic Bluetooth with Serial Port Protocol (SPP) #878

Answers checklist

ESP-AT version

v3.4.0.0-46-g7b9487c2

Operating System used

Windows

If you are using Windows, please specify command line type.

CMD

What is the expected behavior?

By following the instructions at Compile ESP-AT Project Locally and How to Enable ESP-AT Classic Bluetooth I expect to successfully build esp-at firmware, with Classic Bluetooth enabled with SPP.

What is the actual behavior?

The build fails if both "AT bt command support" and "AT bt SPP command support" are enabled using the menuconfig utility as describned in the instructions. However, if I build without SPP selected and only "AT bt command support" selected, the build & flashing succeed and the hardware responds corectly to basic Classic Bluetooth commands.

Steps to reproduce

Following the instructions at Compile ESP-AT Project Locally

cd %userprofile%\esp git clone --recursive https://github.com/espressif/esp-at.git cd esp-at python build.py install choose 1. Platform_ESP32 choose 1. WROOM-32 choose 1: Yes (silence mode enabled, to reduce firmware size) python build.py menuconfig Component config AT -> AT bt command support (selected) -> AT bt SPP command support (selected) Quit with Save = Yes python build.py build

the build fails with a fatal error as shown in logs following and attached iun ZIP file build_logs.zip

More Information

I suspect some years back this was possible (to add Classic Bluetooth with SPP to ESP32 firmware). For example see this description (circa 2021)

However after many weeks of research I fear it may no longer possible as building with SPP always results in an oversized image/firmware size problem, no matter how many tweaks I tried (after studying Minimizing Binary Size)

There are just too many options and tweaks I don't understand, so I'm hoping either for guidance on the correct tweaks, or if necessary, an update to the esp-at menuconfig utiulity with new build options to support BT+SPP+A2DP as was originally intended.

In my perfect world view: there would be a menuconfig option to build a completely Classic Bluetooth focussed, stripped down firmware (e.g no BLE, no WiFi at all). Hopefully this can could be done within the actual firmware size limits and constraints.

"Error: All app partitions are too small for binary esp-at.bin size 0x183a00:"----> From this, it can be seen that the size of the esp-at.bin you compiled exceeds the current app partition. You can disable the AT wifi and mqtt functions that you do not use in menuconfig and try compiling again.

chrisj7903 commented 2 days ago

That makes sense, but can you please specify exactly which options I need to de-select in menuconfig to disable AT wifi & mqtt ? I have tried this idea before but I have no expertise in menuconfig and there are many choices. So nothing I tried fixed my issue.

Luxin812 commented 2 days ago

Find the relevant configuration in menuconfig according to the following path and disable it.

Component config -> AT -> AT wifi command support Component config -> AT -> AT smartconfig command support Component config -> AT -> AT WPS command support Component config -> AT -> AT MQTT command support

chrisj7903 commented 9 hours ago

Two steps forward, one step back ... with WPS, smartconfig, WiFi & MQTT deselected, and with "bt command support" + "bt SPP command support" selected, I successfully completed the build, and then flashed to my ESP32-WROOM-32E.

However it continually loops, starting up briefly then aborts and reboots every couple of seconds. I have attached the looping output below, with abort and backtrace information. If I repeat all the above but leave "bt SPP command support" de-selected I can build and flash OK, and it runs correctly (e.g. responds to AT+BTINIT? )

So the bt SPP capability remains ellusive, and I have no idea what to try next ... help!
