"Grove *1: IIC/GPIO/UART" - No external access to that?

[Kian-kang]

Yes, these are the only ones currently available.

"Grove *1: IIC/GPIO/UART" - No external access to that?

No external access. There is room in the case for a Grove sensor, such as the BME280.

I'm stuck in a boot loop. How can I reset the device fully? The device reaches the Init NRF52 Bluetooth stage before rebooting.

I can view the serial logs.

Hello, after flashing the newest mestastic (2.6.11.60ec05e) I get a blinking blue light but cannot detect device over bluetooth or lora, please advice.

[nfs0619]

Hello! To better troubleshoot your issue, we recommend that you send the flashing logs, device model, firmware version, and detailed steps you followed to our technical support team at sensecap@seeed.cc. This will help us provide you with more accurate assistance.

Hi! Loving my solar node so far! Question: which GPIO ports are exposed through the Grove port? I am creating a custom sensor that uses protobuffs over serial. Also, what is the voltage level for the ports? Is it 3.3V or 5V? I saw that there was a level shifter in the block diagram and I don't want destroy my sensor.

Thanks for your help!

[nfs0619]

Hi! The Grove port exposes D0 (P0.10 / NFC2) and D1 (P0.09 / NFC1).
It provides 5V power, and the IO lines go through a level shifter, so they are 5V-tolerant.
