BLUEHCI_GATT_WRITE_CHARAC_VAL fails

If I issue this command from a BlueNRG acting as a Central to another acting as a Peripheral, quickly after receiving an Indication from that peripheral then the call fails with error code 0x46 (''not allowed''). Experimentally I determine that I don't get this error if I insert a 50ms delay after receiving the Indication. A 10ms delay is not enough.

Can ST please confirm this is an undocumented bug/feature and provide a full explanation plus a recommended work around. Regards - Charles #bluehci_gatt_write_charac_val

Hi Charles,

I apologize, but I'm not able to reproduce your scenario, in attach you can find two scripts (master ans slave roles) that show how a central sends succesfully the command BLUEHCI_GATT_WRITE_CHARAC_VAL after the EVT_BLUE_GATT_INDICATION event is received.

regards,

GM
