1. Bluetooth module Tau fa'asologa
O le fa'asologa o feso'ota'iga e fa'apu'upu'u e pei o se tau telefoni, e ta'ua fo'i o se feso'ota'iga feso'ota'iga, e masani ona ta'ua o le COM port. O se faaupuga lautele lea, ma o fesoʻotaʻiga e faʻaogaina fesoʻotaʻiga faʻasologa e taʻua o ports serial. O se tau fa'asologa o se fa'aoga meafaigaluega.
UART o le faapuupuuga mo Universal Asynchronous Receiver/Transmitter, o lona uiga Universal Asynchronous Receiver/Transmitter.
O le UART e aofia ai le TTL level serial port ma le RS-232 level serial port, ma o masini uma e lua e fa'aoga UART e mana'omia le tausisia o le UART protocol.
2. Bluetooth module UART protocol
E tusa ai ma faʻasologa faʻasologa eseese, e mafai ona vaevaeina atili i ni faʻasalalauga se lua: H4 (TX/RX/CTS/RTS/GND) ma le H5 (TX/RX/GND)
H4: Feso'ota'iga e le aofia ai le toe fa'asalalauina, o lea e tatau ona fa'aoga CTS/RTS. O fesoʻotaʻiga UART o loʻo i totonu o le "transparent transmission", o lona uiga, o faʻamatalaga mataʻituina e ala i le Logic analyzer o faʻamatalaga fesoʻotaʻiga moni Direction Head DataType Host -> Pule 0x01 HCI Command Host -> Pule 0x02 ACL Packet Host -> Pule 0x03 SCO Packet Controller -> Fa'afeiloa'i 0x04 HCI Pule Fa'atonu -> Fa'atonu 0x02 ACL Packet Pule -> Fa'afeiloa'i 0x03 SCO Packet
H5: (fa'aigoa o le 3-wire), ona o le lagolago mo le toe fa'aliliuina, CTS/RTS e filifili. E amata ma fa'ai'u pepa fa'amatalaga H5 ile 0xC0, o lona uiga, 0xC0...payload 0xC0. Afai o le uta e aofia ai le 0xC0, ua liua i le 0xDB 0xDC; Afai o le uta e aofia ai le 0xDB, ua liua i le 0xDB 0xDD
3. Bluetooth module uafu faasologa
Ole tele ole Bluetooth HCI modules e lagolagoina le H5 mode,
O se vaega la'ititi (e pei o le BW101/BW104/BW151) e na'o le H4 e lagolagoina (e mana'omia le CTS/RTS)
Pe H4 poʻo H5, i le taimi o le amataina o le Bluetooth, e fesoʻotaʻi le faʻaputuga faʻapipiʻi ma le module i le saoasaoa o le 115200bps. A maeʻa le fesoʻotaʻiga, e oso i se maualuga maualuga (> = 921600bps). E masani ona fa'aoga 921600/1M/1.5M/2M/3M
Fa'aaliga: O le H4 fa'atulagaina uafu fa'asologa e le aofia ai se siaki siaki; E masani ona fa'aogaina e H5 siaki siaki. Manatua e seti le faatulagaga pe a pu'eina fa'amaumauga o fa'amaumauga tau telefoni fa'atasi ma le Logic analyzer.
4. Tulaga
Faʻamatalaga autu
FSC-DB004-BT826 tu'ufa'atasia le BT826 Bluetooth module ma le DB004 pin interface board, lagolagoina le Bluetooth 4.2 fa'asologa fa'alua (BR/EDR/LE), tu'ufa'atasia le fa'atonu fa'amau, Cortex-M3 CPU, PCB antenna

5. aotelega
O fesoʻotaʻiga faʻasolosolo Bluetooth o se malamalama faigofie ma faʻavae. E masani lava, pe a faʻapipiʻi, faitau ma le faʻaeteete le faʻamatalaga o le module, ma faʻalogo i nisi o mataupu pe a faʻaaogaina le Logic analyzer. Afai e te le malamalama i se isi mea, e mafai ona e faʻafesoʻotaʻi le Feasycom team!
