Description
I'm unable to run any of the getting_started examples on my Modal RV01.
I have tried:
1. Different RX and TX serial cables:
- 6 Ground
- 8 GPIO 14 (TXD)
- 10 GPIO 15 (RXD)

2. Both using ttyAMA0 and ttyS0 (By default, the RVR SDK uses the UART on /dev/ttys0 to communicate with RVR.)
sudo vim /boot/config.txt
add:
...
#dtoverlay=pi3-disable-bt
core_freq_min=500
enable_uart=1
3. Updating to Current firmware version
Current firmware version: 9.1.462, 9.2.482
MAC Address: 00-00-00-00-00-00
Manufacturing Date: 2019/9/14
Hardware Revision: 5
4. Install Sphero SDK GitHub repository for Raspberry Pi
git clone https://github.com/sphero-inc/sphero-sdk-raspberrypi-python.git
cd sphero-sdk-raspberrypi-python
./first-time-setup.sh
5. Used the "use-tty-symlinks" branch
sphero-sdk-raspberrypi-python/sphero_sdk/observer/client/dal/serial_observer_dal.py
...
def init(self, port_id='/dev/serial0', baud=115200):
...and still not able to run any of the examples, I only get the "Checking RVR firmware versions..."
/sphero-sdk-raspberrypi-python/getting_started/observer/driving/drive_target_slewing.py
Checking RVR firmware versions...
Getting default drive target slew parameters...
None
Driving to (0,0) at 0 degrees
Any other suggestions will be greatly appreciated. Thank you!
