Hi,
I'm using nrf Connect mobile (for Android) app to exchange data (read/write) with a BLE device (server) over GATT.
I have a large characteristic (123 bytes) to exchange: no problem when reading. I have problem when I want to write it, the stack raise a 133 error (which is so general!!).
I noticed that, if I select Command radio button (instead of Request) into Advanced options of the Write value mask, the problem disappears, and I'm able to write the value to the characteristic.
Which is the meaning of the "Command" option? This needs me to develop a mobile application and overcome the previous problem.
