Sigfox 武功秘笈第二彈技術大公開

當您的sigfox devie 損壞時，如何更換已購買sigfox 通訊費並完成註冊的模組為另一組新模組，而不需另購通訊費，可延續原模組的使用，這裏示範一下更換的步驟程序：

1.登入sigfox backend 後台網站：

2.選擇 <DEVICE> 選項註冊一組新的device ，需準備好：diece ID 及PAC

3.進入<New> 選項

4.選擇device 所屬的 group

5.填入新Device 的 ID,PAC,device type

6.將新device 設為Prototype( device end product register as a prototype)

 7. 利用Text file 編輯軟體(NotePad)建立一 TXT or CSV 格式檔案，格式如下：
ID_old_device;ID_new_device
原模組devieID,新模組devieID      (可用 ”,”  或 ”;”  或 ”|” 分隔符號區隔)

8. 選<Replace series> 選項，執行deveice 更改 ( Device - Bulk replacement)

 9.選擇要更換的device replacement file : <選擇檔案>

 10. 完成deive ID 替換檔案上傳, 大約5分鐘內新的deice ID 就會生效。

模組省電運作模式說明：

1.      模組供電或RESET_N (RST Pin)送LOW Level 電壓進入標準[Standby]模式。

2.      AT command  <AT$P=1> 進入 [Sleep]模式，可利UART 指令再進入[Standby]模式，或利用 <AT$P=0> 喚醒模組並進入[Standby]模式。

3.      AT command  <AT$P=2> 進入 [Deep Sleep]模式，此時模組進入深睡模式，只能利用模組重新供電或於GPIO9Pin 送LOW Level電壓重新喚醒模組並進入[Standby]模式。

l  UART AT command list總整理

Command	Name	Description
AT	Dummy Command	Just returns ‘OK’ and does nothing else. Can be used to check communication.
AT$SF=frame[,bit]	Send Frame	Send payload data, 1 to 12 bytes. Optional bit flag indicates if WISOL−Sigfox should receive a downlink frame.
AT$SO	Manually send out of band message	Send the out−of−band message.
AT$IF=uint	Set TX Frequency	Set the output carrier macro channel for Sigfox frames.
AT$IF?	Get TX Frequency	Get the currently chosen TX frequency.
AT$DR=uint	Set RX Frequency	Set the reception carrier macro channel for Sigfox frames.
AT$DR?	Get RX Frequency	Get the currently chosen RX frequency.
AT$GI?	Get channel infomation	To get the information on current and next macro channel usage in FCC. //return X,Y X: boolean value, indicating previous TX macro channel was in the SIGFOX default channel Y: number of micro channel available for next TX request in current macro channel. If X=0 or Y<3 send AT$RC  AT command
AT$RC	Reset default channel	To reset the device on the default SIGFOX macro channel (don't use with a duty cycle less than 20 seconds.
AT$CW=uint,bit[,uint_opt]	Continuous Wave	To run emission tests for Sigfox certification it is necessary to send a continuous wave, i.e. just the base frequency without any modulation. Parameters: Name Range Description Frequency 800000000− Continuous wave frequency in Hz. 999999999, 0 Use 868130000 for Sigfox or 0 to keep previous frequency. Mode 0, 1 Enable or disable carrier wave. Power 0−14 dBm of signal | Default: 14
AT$CB=uint_opt,bit	Test Mode: TX constant byte	For emission testing it is useful to send a specific bit pattern. Thefirst parameter specifies the byte to send. Use ‘−1’ for a (pseudo−)random pattern. Parameters: Name Range Decsription Pattern 0−255, −1 Byte to send. Use ‘−1’ for a (pseudo−)random pattern. Mode 0, 1 Enable or disable pattern test mode.
AT$T?	Get Temperature	Measure internal temperature and return it in 1/10th of a degree Celsius.
AT$V?	Get Voltages	Return current voltage and voltage measured during the last transmission in mV.
AT$I=uint	Information	Display various product information: 0: Software Name & Version Example Response: AX-Sigfox 1.1.2-FCC 1: Contact Details Example Response: support@axsem.com 2: Silicon revision lower byte Example Response: 8F 3: Silicon revision upper byte Example Response: 51 4: Major Firmware Version Example Response: 1 5: Minor Firmware Version Example Response: 1 7: Firmware Variant (Frequency Band etc. (EU/US)) Example Response: FCC 8: Firmware VCS Version Example Response: 0 9: SIGFOX Library Version Example Response: UDL1-1.8.7 10: Device ID Example Response: 00012345 11: PAC Example Response: 0123456789ABCDEF
AT$P=uint	Set Power Mode	To conserve power, the WISOL−Sigfox can be put to sleep manually. Depending on power mode, you will be responsible for waking up the WISOL−Sigfox again! 0: software reset (settings will be reset to values in flash) 1: sleep (send a break to wake up) 2: deep sleep (toggle GPIO9 or RESET_N pin to wake up; the WISOL−SIgfox is not running and all settings will be reset!)
AT$WR	Save Config	Write all settings to flash (RX/TX frequencies, registers) so they survive reset/deep sleep or loss of power. Use AT$P=0 to reset the WISOL−Sigfox and load settings from flash.
AT:Pn?	Get GPIO Pin	Return the setting of the GPIO Pin n; n can range from 0 to 9. A character string is returned describing the mode of the pin, followed by the actual value. If the pin is configured as analog pin, then the voltage (range 0…1 V) is returned. The mode characters have the following meaning: Mode Description 0 = Pin drives low 1 = Pin drives high Z = Pin is high impedance input U = Pin is input with pull−up A = Pin is analog input (GPIO pin 0…3 only) T = Pin is driven by clock or DAC (GPIO pin 0 and 4 only) The default mode after exiting reset is U on all GPIO pins.
AT:Pn=?	Get GPIO Pin Range	Print a list of possible modes for a pin. The table below lists the response. Pin Modes P0 0, 1, Z, U, A, T P1 0, 1, Z, U, A P2 0, 1, Z, U, A P3 0, 1, Z, U, A P4 0, 1, Z, U, T P5 0, 1, Z, U P6 0, 1, Z, U P7 0, 1, Z, U P8 0, 1, Z, U P9 0, 1, Z, U AT:Pn=
AT:Pn=mode	Set GPIO Pin	Set the GPIO pin mode. For a list of the modes see the command AT:Pn?
AT:ADC Pn[−Pn[(1V|10V)]]?	Get GPIO Pin Analog Voltage	Measure the voltage applied to a GPIO pin. The command also allows measurement of the voltage difference across two GPIO pins. In differential mode, the full scale range may also be specified as 1 V or 10 V. Note however that the pin input voltages must not exceed the range 0..VDD_IO. The command returns the result as fraction of the full scale range (1 V if none is specified). The GPIO pins referenced should be initialized to analog mode before issuing this command.
