PSoC 4 MCU

New Contributor

Hi

I would like to connect a PSoC BLE to a PSoC 5LP and use the PSoC BLE as a transceiver for the circuit. What would be the best way to connect the two PSoC's and communication protocol to use? UART & AT? SPI?

Thank you in advance

Regards

Paddy

so uart to uart PSoC to PSoC ? Yes, exacttly. For transceivers it is much easier to write a UART protocol. There is no need for you to implement an AT-protocol over UART, you may use your own protocol. For pure sensors (one direction only) it is better to use master-slave constructs as i2C or SPI.

Best choice for a transceiver will be UART. Slaves cannot talk, they only can be questioned/polled for data.

Hi Bob

thank you a always. Just to be clear it's a PSoC BLE I want to use as a BLE transceiver so uart to uart PSoC to PSoC ?
