PSoC™ 4 Forum Discussions

For a project, I read the Received Signal Strength Indicator (RSSI) out of the Advertising Data. My question is, in which relationship stands this value to the absolute value of the Received Signal Strength?

I want to attach a BLE module like PSoC BLE to read the data from an external microcontroller via UART/SPI and store them in various characteristics of a BLE Service ( for eg. I want to read the data via UART rx (PSoC) and store it in temperature measurement characteristic of Health thermometer Service and then transfer this data using BLE HTP(Health thermometer Profile).) Any ideas / documents suggestions how to do it ? In what format the temp values should be sent from the external microcontroller and what should be in the firmware of PSoC to read it correctly ?

Thanks in advance for any help 🙂

hello,

As I am new in BLE and proximity pairing. I would like to know, Is it possible as the BLE central device come in a certain range of BLE slave device automatically give notify about the data. For Example As I have temperature sensor and I am reading the value from the sensor and as any android phone come in certain range of the BLE it give notification of the temperature automatically without need of pairing using cypress BLE PSoc 4 Kit and Cysmart app?

Is there any sample project available?

Thank you!

Hi There,

I have a BLE keypad that measures the user's response speed (in milliseconds) from a START command that it receives from the App.

Obviously the BLE device is very accurate and we have no problem achieving 1 ms accuracy.

However, the START command that comes from the App via the BLE cause an unknown latency which we are trying to address somehow as we aim to build a system that is accurate down to the millisecond.

Any help will be greatly appreciated.

Thanks,

I am trying to use the CyBle_GenerateRandomNumber() function and it always returns the same values.  This is typical of a random generator function but usually there is a function to provide a seed but I cannot find any such function.  How does this function get its seed?  I can live with the device producing the same list of random numbers but I need to know that each separate device will be different.

I try to run RTC many times. I have 2 same function for run as timer one RTC: Timer 1 and Timer 2.

When I run only 1 of it it`s work fine but if I run it one after one ( chain )  second timer not create interrupt to stop.

I tried to use 2 RTC but same result.
