Basically I would like to change the transmit power level during inquiry. So I could kind of dynamically control the physical range of devices that I see. In CSR's Bluecore chip, I think there are pskey that stored the maximum and default transmit power. And there seem to be bccmd psget 0x0017 to get the value. Now my problem is I am using a class 1 dongle using Broadcom chipset. Is there a way to dynamically control the default or maximum transmit power e.g. hcitool cmd 0x.. 0x.. ..... ? During the inquiry paging, does anyone know if they use default or maximum transmit power? Thanks, Edwin Regarding this. I also have the same question I am trying to find answer to ? Want to know if you found the answer. I see three ways of doing this. 1)In the bcm4329 code 2)using bccmd 3)using hcitool cmd 0x0 0x0.. Going through the code can be time consuming And I ll have to go to the theory before I start, Already scimmed through it to see if there is any power control or anything like utility for hw control in the driver , in the drivers/net/wireless/bcm4329 .. I compiled bccmd , But this doesnot support some chips like mine bcm4329 , the bccmd is for CSR chips ,Plz correct me , Mine is not working on the phone. Maybe I ll have to take a clue from the bccmd tool to write my own or check in the code where these pskeys will be. So far I can surmise they are soemwhere in the eeprom. Also this phy.c has some reference to power tables. Need to look carefully. Next hcitool is the option. hcitool I ll look into the ogf and ocf commands in the LMP specifications that I can send, havent tried this. Tell me how did you do it. Just thought I ll send you a mail,if you could plz share your experience regarding this.
