ESP32 Example - Write operation not allowed

[kndndrj]

Hey, first off - awesome work on the library!

Second - I'm not sure if I'm doing something wrong, but when I try running the esp32 - ble_bas_peripheral.rs/ble_bas_peripheral_sec.rs examples, I run into some problems when writing to the custom characteristic.

1. Everything connected to battery level works (reading and notifications).
2. I can read the status characteristic (408813df-5dd4-1f87-ec11-cdb001100000), but I can't find a way to write to it.

Here's how I tried writing to the characteristic (bluetoothctl):

pair FF:E4:...
trust FF:E4:...
menu gatt
select-attribute 408813df-5dd4-1f87-ec11-cdb001100000
read
  -> returns 00
write 01
  -> returns:
    Attempting to write /org/bluez/hci0/dev_FF_E4_05_08_8F_FF/service0020/char0026
    Failed to write: org.bluez.Error.NotAuthorized

I'm using the esp32 board.
Tested with two machines - one running Arch Linux, the other one NixOS.

Am I missing something obvious? Thanks in advance!

Same here, did you figure it out?
