Need help with BLE and ESP32

Hi All,
I try to make an app to send slider and a switch info, through BLE to an ESP32 C3 (with Arduino IDE).
Somehow I managed to send the slider info, but when I use the switch te app crashes.
I could use some help! :slight_smile:

This is my project: Loc1_ESP_BLE_slider_3.aia (193.8 KB)

Hello @DurkV,
honestly I'm not that clever on BLE, nevertheless in your .aia I've seen that you transmit to the ESP32 the status of the switch by using the SendString block.
I would have rather used the SendText, instead.
The link here below, leads you to the example of such use that I've posted a couple of weeks ago.
Probably it can help you.
