Of course, no one should use any of those junk Motorola phones for production - my family company has been making our own FreeCalypso modem boards also since 2017: https://www.freecalypso.org/fcdev3b.html > I have disassembled many old GPRS modules , at last I found this module > is perfect(D751749ZHH). Now I have 500 pcs left As you can read on our website, I have a burning desire to produce our own FreeCalypso-branded modem module: https://www.freecalypso.org/modemmodule.html My idea is to take an existing historical Calypso-based modem module and create our own semi-clone of it. So far the only historical Calypso-based modem module I could find is BenQ M32 (can no longer be bought anywhere I know of, but we have about 40 pieces here at FreeCalypso headquarters), but if you have found a different one (as your pictures suggest), I would be quite interested in taking a look at your module and possibly using it as a basis for my own semi-clone. > there are some picture to share with you. If I am not mistaken, this is the picture you were trying to post as an inline image (this mailing list does not allow attachments or inline images, please post links instead): https://app.2sim.cn/module.jpg However, a datasheet for your modem module would be much more interesting than the pictures - would you happen to have one that you can share? I am interested in seeing the complete mechanical form factor of this module and its host connection interface. > OsmocomBB is running on an ARM board, I think it can run > Magnetite/Selenite also Looking at your pictures, it looks like your modem module has a TI Rita transceiver inside (the RF part behind the Calypso+Iota chipset), unlike BenQ M32 which has a Silabs Aero+ RF transceiver instead. Being Rita-based, your module should be much easier to support in FreeCalypso - I can probably add this support if you send me a few sample pieces of your module plus proper documentation. If you are interested in working with us, please start by sharing some pictures (please post links, NO attachments or inline images!) of just the modem module by itself (without all other junk), both top and bottom views, as well as a datasheet that explains how to connect power and UART interfaces etc. Sincerely, Mychaela _______________________________________________ Community mailing list Community@freecalypso.org https://www.freecalypso.org/mailman/listinfo/community
