Hello,
I am trying to connect two CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kits. One of the boards shall measure a Sensor via the 12 Bit-ADC and pipeline the measured data using the low-energy Bluetooth to the other board. The measurement frequency is 1kHz, so there is every 1ms a new sample. If the data is send to the computer over the UART interface directly for the first board, every sample can be received. But if the data is send over the Bluetooth to the second board and then passed over the UART to the computer only every 7th sample is received. The UART works in booth test with the same baud rate. So the Bluetooth works as bottleneck and slows the transmission.
To connect the second board I`m using the Project #020: UART to BLE Bridge (UART to BLE Central) (https://github.com/cypresssemiconductorco/PSoC-4-BLE/tree/master/100_Projects_in_100_Days/Day020_BLE...). I minimal need a measured data rate of about 80Hz, but while my tests I just got only 66Hz in maximum. Because the minimal BLE4.0 speed is 1Mbps and my data package contains 96bits, I think it should work with a sample frequency above 80Hz. Is there a chance to increase the Bluetooth speed?
Thanks for your help!
Katharina
