Just finished etching the sms controller board. Got most of the parts but still mssing some ICs.  If this becomes successfull, I'll try to port to a pic 16f877 later on. Have to find some time in the next few days to complete all the required components and hunt for some very old 5110s. Sir pcenxa na kase sa school namin mano mano pageetch ng pcb...may sarili ka po bng pcb maker/etcher (anu ba tawag dun) malinis na malinis kase yung pcb design mu e? |

pwede kahit anong microcontroller preferably with built-in RS232 peripheral para madali and also capable of 115,000 bps kung FBUS protocol gagamitin |

sir ask ko po kung sa anung baud rate mo iseset ung uC(encore) mo,?? ung gsm mo eh kunwari gumagana sa baud rate na 4800 (interface sa hypertminal).
dapat ba na 115200 latta ung baud rate ng uC or set mo rin ng 4800??

As per your above example, your uC should be set to 4800. **GSM and uC should be at same baud rate setting. You need also twisted cable (in most cases). |

kung FBUS, pwede kahit di na gumamit ng max3232, like nung ginawa ko dito: Re: help... PIC to 3310 (mas madali ata sa 6210, compared sa 3310) |

Matanung ko nga pala, ano bang advantages ng GSM modem mismo over phones that have modem? Ibig sabihin, AT-commands din ang gagamitin... Pinag-iisipan ko kasi kung dapat pa akong bumili nalang ng modem or punta na din ako sa tipidCP tulad ni YUS...  At sa coding pa pala. Maramirami na din kasi ang mga nakikita kong sample code regarding integration ng gsm modem into MCU, tapos karamihan sa kanila di na hinihintay bumalik yung "OK\r" ng modem. for instance yung command na "AT\r", di ba narereflect ang modem ng "OK\r"? Ano ba ang mas advisable, dapat pa bang hintayin ko yan sa programming ko? Safe bang iassume na dumating na yan at di na hintayin? Nagcoconsunsume pa kasi ng space sa ROMatRAM ng MCU kaya ko lang naman naitanong. |

Nagcoconsunsume pa kasi ng space sa ROMatRAM ng MCU kaya ko lang naman naitanong. I usually check the modem to see if it is still connected. I send "AT" then it should reply with "OK". Pero sa ibang command di ko na chinecheck if magrereply pa ito ng ok ksi nga nacheck na nman na nakakabit pa ung modem. After a certain time of checking at wala reply saka ko ididisplay na "Please connect GSM modem". |

Nagcoconsunsume pa kasi ng space sa ROMatRAM ng MCU kaya ko lang naman naitanong. para sa akin ang advantage ng phones with modem ay presyo, may 300 pesos pag nakatyempo, then gawa lang ng dlr-3p cable ng www.atrox.com konti lang magagastos dun sa response na OK dapat hintayin every time na mag send ng AT commands, isang routine lang naman yan kaya di makunsumo sa ROM |

Because it is not mass produced.
BTW, my bluetooth module could be used as GSM modem alternative.
You only need a bluetooth cellphone and the module can connect to it and use its modem.
The phone will not be touched and damaged and still be usable even after the project is finished.

Really sir? Nice to know about that feature of your bluetooth module. I may have a nice use of that in future projects... |
