for TI WL1251/WL1253 we have driver wl12xx in maemo fremantle already, incl a FOSS version to support monitormode/injection. Schould be easy to port to WL1271, if and porting needed at all. "maemo6" Harmattan (N9) iirc has WL1271. so the TiWi5 sounds pretty good, regarding compatibility. Also powersaving is guaranteed to work on SoC/system level since it's already verified in N900/N9

Also comes with FM-RX: http://www.lsr.com/ProductsWiki/tabid/163/loc/TopicHistory/ShowHistor y/298/Default.aspx?topic=TiWi-R2%2C+TiWi-BLE%2C+TiWi5 (scroll down to "FAQ 1)How do I use the FM Radio on the TiWi Module?") http://processors.wiki.ti.com/index.php/OMAP35x_Wireless_Connectivity _Solution_Hardware#FM_Interface http://www.lsr.com/products-wiki?topic=TiWi+Module+Evaluation+on+the+ Pandaboard N9 Harmattan using this FM feature of "BOB" chip which is wl1271/3 (See N9 schematics page 7) - so driver integration / backporting from Harmattan to Fremantle shouldn't be too hard.

JorJin finally has a new (and better) home page. Their current WiFi modules are here: http://www.jorjin.com.tw/#!wireless/c72v The best matching WiLink6 module appear to be: * WG7311-0A (WLAN/BT/FM) For WiLink 8 a feature list of the chipsets can be found here: http://www.multivu.com/mnr/54040-texas-instruments-ti-wilink8-5-in-1- wireless-connectivity-next-gen-mobile So the best matching modules might be: * WG7831-D0 (802.11b/g/n, BT, FM) * WG7833-D0 (802.11a/b/g/n, BT, FM) * WG7837-D0 (802.11a/b/g/n MIMO, BT, FM) They may be available in samples. Status of Linux driver is unknown. A distributor (not listed there but I know them) is located in Munich.
Comment 9 by Nikolaus Schaller, Jan 15, 2014
I forgot to mention: Part Number: WG7*** Manufacturer: JorJin Features: 802.11b/g/n (a,MIMO), BT 4.0 LE, FM Dimensions: ca. 10-12 mm-sq x 1.6mm Where we can buy samples: distributor in Munich Price per Chip (estimate): ? Linux drivers: ? Other comments: OpenPandora uses an older WLAN module from them
Comment 10 by Nikolaus Schaller, Jan 16, 2014
I forgot WG7351 as a good candidate: http://www.jorjin.com.tw/#!wg7351-00/c1dnh
Comment 11 by Nikolaus Schaller, Mar 1, 2014
Part Number: RS9113 Manufacturer: RedPine Signals Features: 802.11b/g/n + BT 4.0 + Zigbee Dimensions: ca. 14x15x2mm Where we can buy samples: Mouser, Ineltek Price per Chip/Module (estimate): 25 EUR Linux drivers: yes Other comments: appears that we can use USB2.0 to interface it (instead of SDIO) http://www.redpinesignals.com/Technologies_&_Chipsets/Chipsets/RS 9117.php

Here are a few suggestions from Qualcomm Atheros / Atheros based chips. The great advantage: Completetly free drivers with supportive and active developers. I personally find 5GHz wifi mandatory, too, as you cannot have reliable VoIP over 2.4GHz these days. --- 802.11n chips with BT from Atheros: Part Number: AR9462 Manufacturer: Atheros Features: 802.11abgn, 2x2:2, BT 4.0/LE Dimensions: 10mm x 10mm Where we can buy samples: ?

Linux drivers: ath9k Other comments: -> https://wikidevi.com/wiki/Atheros_AR5B22 -> https://www.qca.qualcomm.com/wp-content/uploads/2013/11/AR9462.pdf --- 802.11ac chips with BT from Qualcomm Atheros: Part Number: WCN3680 Manufacturer: Qualcomm Atheros Features: 802.11abgn+ac, 1x1:1, BT 4.0, FM Dimensions: ?

re: #8 http://projects.goldelico.com/p/neo900/issues/546/#ic1641 http://www.jorjin.com.tw/#!wg7831-d0/cxrp WG7831-D0 http://media.wix.com/ugd/0482ec_46d9486932f846829e0f9419495a7bdc.pdf Doesn't mention any FM. We already seen from other modules that those functions might not be supported on module level despite chipset is supposed to provide them re: #10 http://projects.goldelico.com/p/neo900/issues/546/#ic1643 http://www.jorjin.com.tw/#!wg7351-00/c1dnh WG7351-00 is another module based on WL1273, so yes, seems fine. Firmware can get "borrowed" at harmattan of not provided by TI/Jorjin, injection-driver patches as well as "normal" drivers from maemo/meego kernel should work Sidenote; we can't use MiMo, wouldn't know where to place antennas
Comment 17 by Joerg Reisenweber, Apr 30, 2014
re: #14 http://projects.goldelico.com/p/neo900/issues/546/#ic1809 the Qualcom/Atheros are chips, no modules. Thus the 10*10 are already quite large. Nice part: AR9462 seems to offer USB2.0 interface. SDIO interface unclear, instead it offers PCIe, it#s clearly a chip for laptops, not embedded. We need a chip (raher: module) for embedded, with HardMAC and (originat ticket text) "Interfaces should be SDIO (for WLAN), UART (for BT)."
Comment 18 by Linus Lüssing, Apr 30, 2014
WCN3680 has various HardMAC features: http://wireless.kernel.org/en/users/Drivers/wcn36xx Okay, and it uses the pretty new, mac80211 based, now upstream wcn36xx driver, not ath10k. Unfortunately, it looks like its firmware is not free... And it's used by various smartphones already. So it looks like a chip for smartphones to me.
Comment 19 by Werner Almesberger, May 27, 2016
Note: section 5.22.2 of WL18x7MOD data sheet SWRS170H warn that "The correct power-up and shut-down sequences must be followed to avoid damage to the device." http://www.ti.com/lit/ds/symlink/wl1837mod.pdf Note 4 on figure 5-2 then proceeds by requiring that EN be deasserted 10 us before VBAT or VIO drop. The "WL18xx Module Hardware Integration Guide" SWRU437 repeats warning and requirement in its section 4.2. http://www.ti.com.cn/cn/lit/ug/swru437/swru437.pdf I suspect this could be something similar to the power sequencing issue we once experienced in Milkymist, where Flash remained operational while the FPGA's power rails were decaying. This resulted in Flash corruption frequent enough to be a nuisance yet rare enough to be rather hard to find and characterize. There, we solved this by adding a reset generator to a "parent" rail, thus resetting everything before crossing minimum input voltages of the respective regulators.
Comment 20 by Werner Almesberger, May 27, 2016
Addendum: Joerg suggests to use a system-wide SHUTDOWN_PENDING signal derived from VSYS (Neo900.VSYS == WL1837.VBAT), further details of SHUTDOWN_PENDING to be defined.
Comment 21 by Nash Dunlap, Dec 4, 2019
SpeedyPaper once had its own wave on the radio, you can find contacts here https://topwritingcompanies.com/speedypaper-com/ They work mainly for the student audience. Now the radio is not working, but I think they have a WLAN/BT chip.
