Hi,

I want to develop control unit for burner,  kindly advise me, which board kit is near to match my requirements .!

I want to control burner flame with pressure and temperature sensors and three units are attached with burner working.

1: System start up with ( control : Monitor pressure and Temp by sensors )
2: Glow Plug 12v 17A (control : switch on/off with timer + Temp sensor )
3: Blower fan 12V 11A, ( Control : switch on/off + PWM variable speed + temp sensor
4: Fuel Pump 12V, 4A, PWM ( Control : Switch on/off + variable speed + temp sensor

Burner system will start up when Pressure and Temp will reached at desired level.
1st glow plug will on for produce flame , 2nd blower will on with low flow, 3rd fuel pump will on for produce continuous flame,


1: MCU 32Bit Cortex M4 200Mhz
2: Flash 2mb + Accelerator
3: Ram 512
4: 2USB + 2 CAN
5: Ethernet IEEE 1588
6: ADC 8
7: Power on/off 6 Mofsets
8: Temperature Sensor 6
9: Pressure Sensor 6
10: Jtag header
11: TFT controller + LCD
10: I/O 20
11: Multi Function Alarms 4 +RTC
12: PWM 8

Awaiting your helpful reply.

I'm running into issues with pairing/authenticating with a previously bonded device. When I call CyBle_GapAuthReq() when connecting to a new device, the procedure works just fine. However, if I connect to a previously paired/bonded device (bonding required is set with "just works" bonding), then I get the HCI error CYBLE_HCI_HOST_REJECTED_LIMITED_RESOURCES_ERROR when calling CyBle_GapAuthReq().

Is CyBle_GapAuthReq() the correct function call to re-encrypt the connection when I connect to a previously bonded device? Or is there an alternate call based on whether they were bonded or not?

Hi,

I have a BLE central and a BLE peripheral with multiple characteristics.
My BLE central reads the values using CyBle_GattcReadCharacteristicValue( connHandle, readRequestParam ).

Now in the event callback for the CYBLE_EVT_GATTC_READ_RSP event, I can not see a direct way to distinguish, which characteristics values I am getting when I try to read all values at the same time.
I know I can use a state machine approach to read each characteristic one by one and setting the current characteristics handle globally during the read process, but this seems a bit to much hustle.

From my understanding, BLE subsystem (BLESS) runs concurrently with the main loop in the main() function. If both share a variable, is it possible to get a race condition? If it is possible, how to prevent it? Does PSoC creater supplies a mutex like object that we can use to lock/unlock?

Description:

We test our application code (size~ 30KB) together with original hello-sensor sample code (size~8KB);

we find ota time of T(hello-sensor) is Ta  and our application code is Tapp where Tapp > Ta too much.

We observe the reason why Tapp is bigger than Ta is owing to code size during OTA wireless transfer and
synchronous program/erase speed dependent of code size. Besides that, any other bug/reason we can
improve the OTA speed from handset side?

Besides, OTA speed seems to have something to do with OS system on handset like android phone/iOS phone;

how to prevent OTA speed change if user upgrades a higher version OS on phone?

With standard BLE Android has a maximum of usually 6 packets per interval and iPhone 4 per interval. Has anyone tried with length extension on. Does the number of packets per interval increase or stay the same? If it does not then appending multiple packets into a longer one would be the best solution to increasing throughput. If it doesnt would probably be best to leave it as is for compatibility with both BLE 4.1 and 4.2 phones.

Much Thanks,

-Nick
