When I have pluged in my CY5677 at Windows reboot, it falls into a DeepSleep mode and is irresponsive. No reply on the com port. "Unsupported device" in CySmart tool.

The only way I have found to get out of this state is to plug out/in the dongle.

When I do debugging in this state, the program continues in the CySysPmDeepSleep(void) routine after this line:

/* Sleep and wait for interrupt */  CY_PM_WFI;

I can discover trough state LED, that first, when I power up the windows machine, the dongle is in a ready/working state and then while startup comes into this state.

Any idea, how I can wake up the dongle from that state?

(I am using the official CY5677 firmware, BLE_4_2_Dongle_CySmart_256k.cydsn)

I am attempting to allocate the last row of on-board flash (start address: 0x0001FF80) to store non-volatile data (data that survives re-boot). Unfortunately, the bootloader over-writes ALL of on-board flash (0x00000000 - 0x0001FFFF). when loading the application!

Is there an easy way to instruct the bootloader NOT to overwrite the last row of on-board flash?

Hello,

i am working with the Cypress BLE Pioneer Kit. I replaced the original Eval-board with the the CYBLE-022001-EVAL.

The bluetooth HID keyboard example is working. It connects and the simulated battery level ist displayed. When i am now trying to measure real battery levels, i ran into problems.

I connect an power supply to the Port 3.7 and apply 0-1.024V. The reference voltage is selected as internal 1.024V. If i go down to 30% of the voltage the Low power LED goes on. But the battery level which is displayed goes up to 100%.  If i apply 1.024V to the pin the low power LED is off but the battery level is shown as 100%.

It seems to me, that the battery level via BLE is inverted. Where is a good starting point to search for this error in the original example ?

best regards

Lars

I have a custom profile where I want to request a slower connection interval.

I am using HRS example to see how this is done.

In that example, the request is sent from a CYBLE_EVT_HRSS_NOTIFICATION_ENABLED event.

I can not find a similar event for a custom profile.

Does anyone know where I can put my code for this request?

Thanks,

Dale

Hi,    

I have several doubts about the functioning of the BLE.

What is the operating sequence of events generated?

when I give a CyBle_Start (AppCallBack);
I know that the first event generated is CYBLE_EVT_STACK_ON in which I send the device goes into Advertisement ... from that point my doubts arise, there are several events that can occur in the bluetooth stack, I know there is documentation and API available, but it is not clear when these events occur and how they should be used. I try to look at the examples, but each is implemented in a different way.
If possible explain step by step for each connection phase, how to read, write and report ...

an example of error that could not understand the reason is when I try to modify the Intervalor connection (my device is a type server peripheral) When I connect to the dongle using the cysmart appears on the screen the request to change the connection interval if I accept the request the services and features are unread and a timeout error and disconnects. If I do not accept the connection request interval change the device connects normally.

Thanks for listening!

I have designed a 2 layer PCB for touch sense as per  the directions given in the datasheet. Can someone verify the design and suggest any changes .I will be using a 2mm acrylic overlay on top of it. This PCB will connect to main board using a short 6x2 cable.

All the dimensions are in mm and the isolation between pads and ground is 1.8mm. I want to use the center larger pad for activating other pad scanning so in low power mode controller will be scanning only the center pad.

Hi,

I'm playing around with a psoc4m pioneer kit, and I'm trying to initiate a dma transfer from a buffer to a gpio port data register (CYREG_GPIO_PRT0_DR). I couldn't find any documentation specifically saying this won't work, but I haven't had any luck so far. If I'm not using DMA, I can write directly to the port register no problem. Any thoughts? Thanks.
