I am building a BT Classic audio application using the Bluegiga WT32i module. Our application uses a headset in HFP profile that can get paired to several WT32i modules in HFP-AG profile. The WT32i modules in HFP-AG profile are at least 6-7 feet (2 meters) apart from each other. This far, I have envisioned two (2) BT PAIRING schemes that require two (2) different BT POWER parameter settings.
Set the BT POWER to maximum dBm (6 6 6) and have the user selects which WT32i module in HFP-AG profile s/he would like to connect to no matter how far s/he is from it. (this is limited by the maximum range of the WT32i module, which is 80 meters on average in all directions in open space at a height of 1.4 meters)
Set the BT POWER to minimum dBm (-18 -18 -18) and the user automatically pairs to the closest WT32i module in HFP-AG profile as s/he gets closer to that one vs. another one.
My question is: for schemes 1 and 2, what are the iWRAP parameters that I need to enter into my serial terminal to configure the WT32i module in HFP-AG profile and have it behave as described above?
I have bought new BLED112 for GATT server which will use in Automative Domain. For start-up, I found example of usbcdcin SDK. And I have updated Hardware and GATT profile as per my requirement. Then I create a hex file and flash on BLED112 in DFU mode. But after flashing my dongle is not detected in PC. I have attached my profiles.
I have also query about GATT profile. What is id in characterisics? Where it is used? I have read/write/notify characteristics with non-constant value then do I need to create new BGScript or I can program with BGLib and BGApi. Please provide some links to start with BGLib and BGAPI in C. How I can get any characteristics call back and how I can set time for notify.
I am using a WT32i developmentKit as a bluetooth source. all instructions work properly, but when i try using AT COMMAND, i get only 'SYNTAX ERROR'.
The 'AT' command can still respond with an 'OK'. And i have already established a HFP connection between my WT32i and a headset.
So i have follow questions:
1)Does WT32i have a enable setting for AT COMMAND?
2)How can i successfully run a AT COMMAND?
3)In may case, i wanna a headset battery indication. Can i have any other ways to implement this except a 'AT+IPHONEACCEV'?
My current solution is to disconnect the HFP connection and then reestablish it so i can get a 'AT+IPHONEACCEV' response.
I'm waiting for your answers. Thank you!
I am using two WT11 module with iWRAP version 5.6. After sending the CALL command i got this error "RFC_CONNECTION_KEY_MISSING" , so i tried to pair the devices again , the same error persist, how can i fix it ?
I use on my new devices BLE112 module. In production all processes are automated. But I have a problem to program new firmware and get adress on BLE112.
I would like to integrate into our production software or Labview(national instrument) the BLE112 programmation.
Do you have a dll to communicate with cc debugger and BLE112 or do you have bleupdate-cli sources ?
All my questions are in the title. I am currently working on a project that needs, among a lot of others things, the output power of the bluetooth to be programmable. Is it possible with the BGM11S like it is with the BLE121LR? I didn't find any information on its datasheet, maybe because it is not possible actually but I would like to be sure. If so, is that value may be changed using OTA (which is not possible with BLE121LR apparently) ?
Thank you !
I understand that this is a very novice quesiton but I'm new to the C SDK and C in general.
I would like to use UART for debug during development. I had found this post but it no longer seems relevant with the 2.6 SDK.
I can find most of the reffered files in /Applications/Simplicity\ Studio.app/Contents/Eclipse/developer/sdks/gecko_sdk_suite/v2.0/hardware/kit/common/drivers
but not all, for example I'm missing: retargetserialconfig.h.
Also after doing step one it already says: retargetserial.h no such file or directory while I can clearly see it listed in the project.
I would very much apriciate it if the guide could be updated for the 2.6 SDK.
I have bought new BLED112 for creating GATT server. I am new to BLED112. I have below queries,
I tried to connect two WT11 BT module with the same iWRAP version ( 5.6 ), the connection could not be established, when i tried with two WT11 modules with different IWRAP version iWRAP 5.6 and iWRAP 4 the connection succeeded. i am really confused, how to fix this issue ?
On Saturday we'been outside to make some troughput measurements. It's was freezing cold. Roughly about 0°C. After 10 minutes the performance of our SLWSTK6020B dropped and than it stopped working completly.
Every variation of the EFR32BG13 works till -40°C. What about the Developer SLWSTK6020B board? Couln't find it in the specifications. Or was it just the battery? That would be sad. A board wich can handle -40°C but its batterie couldn't. Any other ideas?
