Hello, I've a Nano 33 BLE acting as a BLE Peripheral. I can connect and read characteristic but I can't write to it.
I've tried different examples (e.g. CallbackLED), but always same issue.
I've tried both RF Connect and LightBlue app on Android phones.
I've read about similar issues on the forum but I wasn't able to find a solution.
Any ideas?
Welcome to the forum
You need to define your characteristic with the BLEWrite property. See the library documentation for all options. Just us the OR operator to combine them.
BLECharacteristic myCharacteristic( MY_BLE_CHARACTERISTIC_UUID, BLERead | BLEWrite );
If that does not solve your issue. Please post your code. Use code tags (should look like my example).
