Troubleshooting

Generally, if communication is absent, intermittent or slow, follow through this common list of possible quicks:

• If necessary use common ground for each device
• Check software pin configuration
• Check physical pin wiring connection
• Check device id configuration
• Other tasks are occupying all the available loop time
• Uncorrect packet length passed to send
• Forgot to call update() or receive() ?
• Calling update() and having defined #define PJON_MAX_PACKETS 0?
• If using SoftwareBitBang add a 1-5MΩ pull-down resistor if not present

If you haven't identified the problem or you are a more advanced user, porting a new device or strategy see the strategy related troubleshooting page.
