I tried to run BLE Server example as described in Rui’s book “Learn ESP32 with Arduino” but on my phone I see just one Characteristic “Humidity”. When I comment rows about ‘Humidity’ I get the “Temperature” Characteristic. More over instead of ‘Service UUID: 91bad492-….” I see absolutely different one ‘Service UUID: 4fafc201-….’. Same situation with Characteristic UUID. I’m using a ‘Wemos’ ESP32+OLED board, but I have the right board chosen as all the examples until now running well. What’s wrong?
Obviously my board differs from WEMOS LOLIN32, as sugested the Chinese manufacturer, as same project runs on an other board well. Sorry to disturb you!
Hi Svetlin, sorry for taking so long to get back to you and you don’t disturb, I’m happy to help!
Does the exact same sketch work fine on another ESP32 boards? Does it stop working with the WEMOS LOLIN32?
Can you post the UUIDs of the services that you see?
Thanks for your patience!
