I have a bluenrg-1 as a central and a smartphone as a peripheral. Central can connect and discovery correctly.
When I try to write a pheriperal's value, aci_gatt_write_char_value() return 0x01.
aci_att_prepare_write_resp_event is never called
aci_att_exec_write_resp_event is never called
but the peripheral is receiving the data!
What is the error code 0x01 ?
