Updating the BLE_server code in ESP32_BLE_Arduino repo

[SindhujaNarra]

Hello @nkolban,

I had faced the same issue (#144) as @weizenbock when I was testing BLE_server and BLE_client in Arduino IDE with 2 ESP32 DevKitC devices (one as the server and another as the client). It worked only after I made changes to the BLE_server code as suggested by @chegewara i.e., to reduce the length of device name to 3 (5 characters device name didn't work for me) and adding "pAdvertising->addServiceUUID(pService->getUUID());" to the code.

I have seen that few others have the similar issue (#144 #145 #163). So, I was wondering if you could please update the code for BLE_server in ESP32_BLE_Arduino repo so that in future no one else faces this same issue.

Thanks

you can do it on yourself:

Part of my script:

copy the \cpp_utils\BLE*.* and \cpp_utils\HIDTypes.* files to your Arduino hardware\espressif\esp32\libraries\BLE\src directory

delete the \BLE\src\BLEExceptions.* again (or do not copy it :-) )

comment all lines of #include "BLEExceptions.h" -> //#include "BLEExceptions.h"
also comment the lines beginning with throw new BLEUuidNotFoundException and throw BLEDisconnectedException();

enjoy

@nkolban : maybe you can set the exception-handling in the not #defined part for the Arduino IDE !?

This worked for me: pAdvertising->addServiceUUID(pService->getUUID()); before pAdvertising->start(); (my device name is 20 characters no problem)

@devinsewell And i can tell that your UUID is 16 bit type, but when you want to addServiceUUID with UUID 128 bit long it wont work. I will fix it soon, but there is many more important bugs and issues to fix.

Ah the 20 character device name worked then stopped, changed to a 3 character name it fixed
