The VDD supply is shared between RF transceiver, BLE and WIFI via jumper P5. Shunts must be placed in appropriate positions as shown in the following figure to power up different blocks. P5 can also be used for measuring current flowing through different rails by connecting an ammeter between VDD and VDD_RF/VDD_BLE/VDD_WIFI. 32 pin Hirose connector The Hirose connector P1 interfaces the EV-COG-BLEINTP1Z board with the MCU Cog. The connector carries VDD, UART, SPI2 and GPIO signals from MCU cog board.

Install the jumper between VDD_BLE and VDD in addition to VDD_RF Bluetooth Low Energy Chipset The EV-COG-BLEINTP1Z has a Bluetooth low energy chipset EM9304 from EM Microlectronic. The chipset contains BLE protocol stack along with some profiles. The MCU cog communicates to EM9304 by means of SPI2. The user will need to send BLE configuration commands and data over SPI. The following table captures the signals connected to EM9304 Component EM9304 pin number EM9304 pin name MCU cog signal U1 4 ENABLE GPIO27 15 GPIO0 SPI2_CS0 16 GPIO1 SPI2_CLK 17 GPIO2 SPI2_MISO 18 GPIO3 SPI2_MOSI 20 GPIO4 SPI2_RDY The Jumpers P6 and P7 are provided to isolate SPI_CS and SPI_CLK lines connected to BLE while working with RF transceiver daughter cards. But shunts must be placed on these jumpers for BLE to work. WIFI module connector The connector P9 supports the WIFI module ESP8266. The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack. The module communicates to MCU cog via UART TX and UART RX lines. Each ESP8266 module comes pre-programmed with an AT command set firmware which allows easy programing over UART.
