  1. Hi everyone, I bought a PmodESP32 evaluation board to test the ESP32 module. In my project I would like to use classic bluetooth (no low energy). When I power up the system and do a scan with a smartphone, the ESP32 module does not appear. If I try to use the AT commands (AT + BTINIT ...) the module replies with an error message. I'm pretty sure the system firmware needs to be updated, so i tried to do a firmware upload but without success. I used various software (Arduino, ESP DOWNLOAD TOOL V3.8.5) but during the procedure it seems that the module is not recognized.
  2. I purchased a PMOD-BT2 recently and since (according to your documentation) the SPI connector uses the same power as the regular PMOD connector, I though I could just connect it via the SPI header (not supplied), for programming. Strangely enough, the FPGA board (a Nexys4-DDR) would not power up. An investigation reveals a strange fact: according to an ohm-meter the power on the SPI header is reversed compared to your documentation. I would appreciate it if someone from Digilent could confirm this from the PCB schematics and update your documentation ASAP, as well as issue an errata, because c
  3. Hey Guys, Im trying to connect HC05 Bluetooth module to my arty board. For this reason, first I implemented a serial module to read data, then I connect an HC05 module to the Arty board via Pmode connectors (Pmod jb connectors): set_property -dict {PACKAGE_PIN E15 IOSTANDARD LVCMOS33} [get_ports {UART_TX}]; set_property -dict {PACKAGE_PIN E16 IOSTANDARD LVCMOS33} [get_ports {UART_RX}]; about serial port, I am 00% sure it works properly with baud rate 9600 because I checked it first with a USB port serial communication and it works perfectly. the program is as follow: I
  4. Hello, I'm working on a school project with the Digilent Pmod BT2 and I'm having problems trying to change certain settings while in command mode as well as using the inquiry command. My goal is to initiate bluetooth connections from the pmod BT2 module while in master mode rather than to have to initiate the connection from the secondary bluetooth device while the module is in slave mode. I'm using the application putty for my command line, and I am able to enter command mode just fine (I type in $$$ and receive CMD back) but when I try to change the authentication settings I enter SA,
  5. Hi, I recently purchased the pmodbt2 bluetooth interface module and tried interfacing it with the Atlys board. I used the GPIO demo bit file which was given in the forum for verification (after modifying it), but I was not able to see the output in the terminal software (Teraterm). I followed the instructions given in the demo, but I was not able to see the output; are there any specific changes I need to make in the module or in the terminal software? Can someone help me out with this? Ishan
  6. I have been working hard to understand the RN-42 device on the Pmod BT-2 with very little success. The Goal: To implement a pair of BT2 modules in a BAN (body area network) under PIC micro control at both ends. The present Scenario: I have been trying to take a modular approach to this project. Currently, I have two BT2 modules each plugged into a Microchip explorer8 Pmod socket on two separate boards. At present there is no active MCU on either board, instead I have patched the RxD and TxD to the pins of the USB to Serial interface. In this way, I have been able to access the modul
  7. Hi, We would like to implement bluetooth capabilities on our FPGA (nexys3) board. We want an app on our mobile phone to be able to transmit and receive data to/from the FPGA. We have tried looking for sample codes all over the net but we couldn't find any. Hope that any of you guys have experience working with this pmod module. 1) How should I go about implementing this in verilog? 2) For the app, is there data formatting to be done on the phone application? I'm looking at the default slave mode for this application. To use this mode, do I need to enter command mode, and transmit '$$

    PMod BT2

    I have just purchased a PmodBT2 but I confused as to the pin numbering. J1 is marked with Pin-1 but along the row does it go in numerical sequence 1,2,3,4,5,6 and start from the row next to Pin-1 as 6,7,8,9,10 or is it alternate as in 1,3,5,7,9,11 and 2,4,6,8,10,12 along the other row? Also the DS states that J1 6 & 12 are connected to J2-6 but, on measuring I have J1-6 & 12 joining to J2-5 !!!

    Basys3 Bluetooth

    Hi guys, I really need to connect basys3 with bluetooth. However, I have no idea how to do that. Please help me
  10. Hello, I am using a Nexys 3 FPGA and the PmodBT2 for a university project. I am eventually going to transmit my custom data processed by the FPGA but for now I am trying to get the Bluetooth working. I downloaded and configured the PmodBT2 example from this website HERE but I can't seem to get it to work. I am using an Android phone with BlueTerm and I am having issues connecting my phone to the PmodBT2. I can successfully pair the devices, however I cannot get them to connect to each other, and therefore when I push the buttons or use the switches on the Nexys 3 board I do not see anythi
  11. An engineer at Microchip Taiwan made bluetooth shield which can be controlle through Android. Here are sketch and Application Development Kit (APK) which can only be installed on Andriod 4.3 #define KitLED 2 // APP-ESS14-2 : D8 #define KitWakeupHardware 11 // APP-ESS14-2 #define KitWakeupSoftware 12 // APP-ESS14-2 #define CMD_MLDP 13 // APP-ESS14-2 void setup() { pinMode(PIN_LED1, OUTPUT); pinMode(PIN_LED2, OUTPUT); pinMode(KitLED, OUTPUT); pinMode(KitWakeupHardware, OUTPUT); pinMode(KitWakeupSoftware, OUTPUT); pinMode(CMD_MLDP, OUTPUT); Serial1.begin(115200); } voi
