Fwiw, i did a quick google of that devices ble chip `CC2540` Vs the `hm10` (I own 2 of these )

Seems they are the same device basically. If this is true, I’ve been in contact with the hm10 manufacturer and they have verified this device can’t write to or update the readable characteristic via the code. It only notifies.
