Выбор Bluetooth для NOVA/CX-20

Прошу помощи в выборе блютузного модуля. Что-то никак не складывается картина, вроде везде в роликах и инструкциях использует народ HC-06, а здесь продавец рекомендует HC-05.
пс.
Ни в коем разе не реклама продавца, просто берется большой заказ и хотелось бы получить быстро в нём же и модуль.

 

Да, в принципе тут можно и взять два.
Хотя более склоняюсь к НС-05, судя по описанию может работать в режиме master-slave, а НС-06 только в
режиме slave.
Скопировал сюда их описани, может сгодятся.

Спойлер: НС-05

SWireless Serial 6 Pin Bluetooth RF Transceiver Module HC05 RS232
Size: 45mm x 17mm x 6mm (L x W x H) (Approx)
Cable length: 20cm
It is HC-05 Bluetooth module.
Operating voltage: 3.3V
Working current: matching for 30 MA, matching the communication for 8 MA.
Use the CSR mainstream bluetooth chip, bluetooth V2.0 protocol standards.
Potter default rate of 9600, the user can be set up.
With computer and bluetooth, bluetooth adapter, PDA, seamless connection equipment.
Dormancy current: no dormancy.
input power supply 3.3~6V, Prohibit more than 7V.
Commercial Series: Bluetooth module board Series
With LED indicator light, use 150mA and 3.3V regulation chip.
With VCC, GND, TXD, RXD foot for the Bluetooth
With "Re-search" button (ON/OFF/WAKE foot for it , external MCU out input "High level" can control module to re-search)
Compatible with bluetooth master module", slave module" or master-slave (whole) module.
Allows your device to both send or receive the TTL data via Bluetooth technology without connecting a serial cable to your computer.
No "Automatically prevent power supply peversing func", so please correctly connect power supply

Slave HC-06 Wireless Bluetooth Transeiver RF Module Serial+4p Port line M8

1. using HC-06 slave module, core module, which leads to the interface includes VCC,GND,TXD, RXD, reserved LED state output pin, MCU can state whether the bluetooth is connected through the foot, slave KEY pin is invalid
2. the led indicator bluetooth connection status, twinkle said there was no bluetooth connectivity, Chang Liang says the bluetooth is connected and turned on the port
3. plate set meter diode with 3.3V ", as the input voltage 3.6~6V, unpaired current about 30 ma, matching after about 10mA, no more than 7V input voltage!
4. interface level 3.3V, can be connected directly to all kinds of single chip microcomputer (51, AVR, PIC, ARM, MSP430, etc.), 5V single chip can be connected directly, without MAX232 couldn't through MAX232.
5. clearing the effective distance of 10 meters (power rating is CLASS 2), more than 10 meters is possible, but I don't have distance connection quality
6. after matching when full duplex serial port to use, do not need to know any bluetooth protocol, but supports only one in the eight data bits, stop bits and parity checking the communication format, which is the most commonly used communication format, does not support other formats.
7. when the bluetooth connection has not been established support by pairing the AT command set baud rate, name, password, set the parameters of the power save. After the bluetooth connection automatically switch to passthrough mode
8. small size (3.57cm*1.52cm), SMT factory, ensure the quality of the patch. And set transparent heat shrinkable tube, dust and beautiful, and there are some antistatic ability.
9. the link is slave, slave and all kinds of computer with bluetooth function, the bluetooth host, most with a bluetooth mobile phone, PDA, PSP and other intelligent terminal matching, between the slave can not match.
