Hello,
has anyone tried to make a ble connection between a ESP-WROOM-32 and another ble device?
If yes, how do I have to configure the characteristics' attributes in order to write to them?
My problem is being able to write to any characteristic.
Is there anything I do wrong?
Thanks in advance for ...

Anyone having problem with at command AT+BLEGATTCWR ??

I run the ESP-AT on ESP-WROOM-32

I wanted to write some bytes to the following characteristic (I skipped the other ones):
AT+BLEGATTCCHAR=0,3<\r><\n>
+BLEGATTCCHAR:"char",0,3,2,0x0003CDD200001000800000805F9B0131,0x04<\r><\n>
