Firmware programming User is able to program their own developed firmware (with SDK) into PRBMD0x. The programming procedure is as following, programming software, PhyPlusKit.exe (for window) must be pre-installed, and UART-USB dongle may be needed: 1. 2. 3. 4. 5. 6. Connect TM pin (pin 10) to 3.
GPIO and interfaces Every GPIO can be configured as Input, Output and Interrupt, and can also be configured as weak pull-up, strong pull-up, weak pull-low or floating mode. Except ADC, all interfaces are possible to map to different GPIOs by software. The interface including: 1. I2C: it supports 100KHz and 400KHz modes, 7-bit and 10-bit address 2. I2S: either master or slave mode can be enabled 3. UART: Asynchronous Rx/Tx, up to almost 1Mbps, supports parity and 9 bit-data 4.
RF characteristic PRBMD02 RF characteristic is illustrated as following: PRBMD02 DATASHEET 1.

Points to note • IO pins pull high/low resistance: - Floating: Hi-Z - Strong pull up: 150KΩ - Weak pull up: 1MΩ - Pull down: 100kΩ • P1, P15, P16, P17 do not support FullMUX, and only treated as GPIO. • Except TM/ P16 and P17, all GPIO support interrupt and wakeup • Single-end ADC pins: P11, P23, P24, P14 and P15 • Differential ADC pins: P18-P25; P14-P24; P20-P15 • Two modes available for ADC: bypass and attenuation: - By-pass mode Without attenuation, input range should be 0-0.
Firmware information PRBMD02 DATASHEET 1.
Default firmware PRBMD02 comes with default UART-BT firmware, allowing user able to enable their product with BT feature without any extra engineer resources. The firmware basic feature is to tunnel data between UART port and Bluetooth device (Transparent mode). User can develop their own firmware by SDK as well if default firmware is not applicable. AT-CMD and Transparent Modes The firmware contains two modes: AT-CMD mode and Transparent mode.
Mode switching The switching between AT-CMD and Transparent mode is automatically. When PRBMD02 is NOT connected with smartphone, tablet…, PRBMD02 will enter AT-CMD mode and AT-command will be accepted from UART port; and once PRBMD02 is connected to with smartphone or any other BT device, PRBMD02 will automatically go into Transparent mode, and all data from UART, even AT-CMD, will be treated as data and send out to BT side.
AT-command AT-command in AT-CMD mode are listed as below: BT related UART and GPIO Action enquiry return value set set/get ID AT+ID?

Firmware programming Tx Rx 3.3V USB-UART dongle Note: Some USB-UART dongle may have different definition of Tx and Rx, can swap these pins if not success PhyPlusKit interface Note: More information will be described in PRBMD0x Programming document. MAC address Unless otherwise instructed, each PRBMD02 will be shipped with KATP preprogrammed but no MAC address is pre-programmed. User can program their own MAC address by PhyPlusKit.
Mounting guide PRBMD02 is RF sensitive; in order to obtain the best performance, it is recommended to mount the module at corner of mother board, and with some marginal space. Also, keep it away from metal components, such like speakers, transformers, batteries, big aluminum capacitors, heat sinks and Metal Panels. The figure below illustrates how to mount the PRBMD02 module. Improper mounting will decrease the RF performance dramatically. PRBMD02 PRBMD02 DATASHEET 1.
Evaluation Board Evaluation board (EVB) is available, helping engineer for the firmware development. It is in DIP form factor, allows engineer to connect with external circuit easily for debugging and testing. EVB for PRBMD02 is same as EVB for PRBMD00, and an adaptor board that convert PRBMD02 pin to connect with the EVB The EVB is illustrated as following: 50mm PRBMD02 on adaptor board 30mm The EVK is in DIP format with PRBMD02 (and adaptor board) on it, and with on board 32.
USB-UART LED TM jumper module LED Reset button VBUS 1. 32K jumper: Since P16,P17 are multiplex with external 32.768KHz oscillator, this jumper allows the PRBMD02 to connected with the on board 32.768KHz oscillator. 2. LED & UART jumper: This jumper allows the module to connected with on-board LED and the on-board USB-UART chip. Connecting 5V allow PRBMD02 to be powered from USB. Connecting 3V3 will provides a 3.3VDC to the rest of the board 3.
PRBMD02 DATASHEET 1.
Firmware development and SDK User is allowed to developed their own firmware for PRBMD02 through SDK as following: 1. copy SDK to a working directory 2. install MDK Keil5 for ARM IDE 3. Example code in SDK can now be edit and compiled. Experience on ARM core firmware development will be very helpful for development the firmware.
Service Firmware programming K-Solution provide pre-programming service, so that PRBMD02 will be shipped with firmware pre-programmed. Service charge is needed. Software service from K-Solution K-Solution also provides firmware develop service for PRBMD02 module, hence customer do not need to spend their resource on the firmware development. These services requires NRE charge. For the details, please contact our local sales representative or distributor.
