content: Hello everybody, I don't know precisly if Im right here, but ok.Im currently trying to reversengineer airbeacon.me, Indigogo site:www.indiegogo.com/projects/irbeacon-smarter-remote-for-a-smarter-home/, notbecause I want to sell my own, because it is crap and works with a delay of like 2 secs.So I took one of thes units apart and I found a bluetoothmodule with this text on it:CSR1010 (last 0 might be a "Q")A05U419AGNow I'm struggeling with identyfying the bluetoothmodule on there, can somebody please help me?Currently Im trying to trace all the lines but can't do that because I still didn't got my solderingstation to desolder the BTModule and the battery case.Thanks for the helpFelixPS Immages will follow as soon as I get them from my phone to my PC so maybe 10 or 20 minutes

content: It is obviously made by CSR -www.csr.com. Look for whatever information you can find there.AlsoQuoteSo good luck finding any documentation

content: ATMega328 makes me think that this thing has some Arduino roots.Have you tried to read out the firmware? Is device locked?

content: QuoteI think so too.QuoteI tried but havent got there... the Programmerheader has a pretty small pin pitch and IA) Don't have a connector for it andB) Its hard to connect it to my AVR ISP II without shorting out everything...

content: The pin header doesn't look that small?The device is a module, don't worry about the chipset, it's a CSR chipset alright, but it's pre-installed on a module, are there any identifiers on the module?Look for a BT LE module on ebay and I expect you will find it.I expect the 328 runs a arduino sketch which talks to the BT unit over AT commands or HCI, or something else, and then modulates an IR signal out of the IR LEDIt looks to essentially be a BT LE to IR translator

The whole thing is about 30x30mm big.Quote from: Wilksey on February 13, 2016, 10:33:30 pmOn the Module itself not exept the labes on the labes on the pins, and a label on the PCB: "BT_4.0" well... helps not so much.I would be happy if I could get a pinout diagramm for this module... I got the power supply and the UART bus pins, I hope I get my solderingstation soon so I can attach there a few cables and read out that protocoll.Quote from: Wilksey on February 13, 2016, 10:33:30 pmThats the exption I got to... but I hoped to find in there something like a D21 or a PIC...
