Using BOOST-CC2564MODA with bluez on Linux

I’m trying to get the CC2564MODA working with NuttX, then I decided to test it with Linux’s bluez first to guarantee it is working.

I used a CP2101 USB/Serial dongle, connected RXD to BUTX1, TXD to BURX1, CTS to BURT1, RTS to BUCT1.

Unfortunately the CC2564B will not work correctly if you don’t load a patch to fix its internal firmware. I download the file cc256xb_bt_sp_v1.6.zip from TI site extracted and copied it to:

$ sudo cp ~/CC2564/CC256XB_BT_SP/v1.6/initscripts-TIInit_6.7.16_ble_add-on.bts /lib/firmware/ti-connectivity/TIInit_6.7.16.bts

Next step is to use hciattach:

$ sudo hciattach -s 115200 /dev/ttyUSB0 texas 115200
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_6.7.16.bts
Loaded BTS script version 1
Device setup complete

Open a new linux terminal and run:

$  sudo btmon
Bluetooth monitor ver 5.37
= New Index: B0:B4:48:F4:A1:54 (BR/EDR,UART,hci1)               [hci1] 0.270465
= Open Index: B0:B4:48:F4:A1:54                                 [hci1] 0.270467
= Index Info: B0:B4:48:F4:A1:54 (Texas Instruments Inc.)        [hci1] 0.270467
= New Index: E0:06:E6:CF:FD:CE (BR/EDR,USB,hci0)                [hci0] 0.270468

Open another terminal and run:

$ sudo btmgmt --index 1

[hci1]# auto-power
Found controller with index 1

Note that I used “–index 1” instead “–index 0” because the BOOST-CC2564MODA was included as “hci1” (my laptop has Bluetooth internally).

Finally we can search for BLE devices:

[hci1]# find -l
Discovery started
hci1 type 6 discovering on
hci1 dev_found: BC:6A:29:AB:3F:46 type LE Public rssi -50 flags 0x0000 
AD flags 0x05 
eir_len 3
hci1 type 6 discovering off

Debugging NuttX BLE on BOOST-CC2564MODA board

I am testing the NuttX’s BLE on CC2564 but it is failing for some unknown reason:

How to install NuttX on Nordic nRF52832

Today I tested NuttX on Nordic nRF52832 and it worked fine!!!

I used this low cost nRF52832 module:

https://www.ebay.com/itm/nRF52832-Bluetooth-4-1-BLE-Module-M4-Transparent-Transmission-CORTEX-M4-512KB-/332270581440

First you need to clone, compile and install a recent OpenOCD.

I used this mirror from github because I was facing issue with main repository:

$ git clone https://github.com/ntfreak/openocd
$ cd openocd
$ ./configure --enable-aice --enable-amtjtagaccel --enable-armjtagew --enable-cmsis-dap --enable-dummy --enable-ftdi --enable-gw16012 --enable-jlink --enable-jtag_vpi --enable-opendous --enable-openjtag_ftdi --enable-osbdm --enable-legacy-ft2232_libftdi --enable-parport --disable-parport-ppdev --enable-parport-giveio --enable-presto_libftdi --enable-remote-bitbang --enable-rlink --enable-stlink --enable-ti-icdi --enable-ulink --enable-usb-blaster-2 --enable-usb_blaster_libftdi --enable-usbprog --enable-vsllink
$ make
$ sudo make install

Now we can clone, configure and compile NuttX on nRF52832:

$ git clone https://bitbucket.org/nuttx/nuttx
$ git clone https://bitbucket.org/nuttx/apps
$ cd nuttx
$ ./tools/configure.sh nrf52-pca10040/nsh
$ make menuconfig
$ make

$ ls -l nuttx.bin 
-rwxrwxr-x 1 alan alan 61016 Abr  3 20:07 nuttx.bin

$ arm-none-eabi-size nuttx
   text	   data	    bss	    dec	    hex	filename
  60793	    220	   1972	  62985	   f609	nuttx

Now we can flash nuttx.bin in the board.

To program this board I used a stlink-v2 clone. I connected the SWDIO (board pin 33), SWDCLK (board pin 32), GND (pin 9) and VCC (pin 10) to respective pins of ST-LINK V2 programmer. Note: I connected VCC to 3.3V.

$ sudo openocd -f interface/stlink-v2.cfg -f target/nrf52.cfg -c init -c "reset init" -c halt -c "nrf5 mass_erase" -c "program nuttx.bin verify" -c reset -c exit

You can see the NuttX starting in the serial console configured to 115200 8n1, just use a USB/Serial of 3.3V connecting P0.24 (board pin 36) to RXD, the P0.23 (pin 35) to TXD and the GND (pin 9) to USB/Serial’s GND.
