"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.

[EntropyWorks]

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,
You can try reflashing the firmware to see if this resolves the issue:

Has anyone solved this problem? I have the same problem.

[kugghjhulsmojj]

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 [email protected]. 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.

Hi, after 10 weeks working fine I can't connect via BT to the solar node. I guess the panel did not deliver enough energy. So I connect a charger but still can't connect. Tried different mobiles... And power off/on, but...
any hints?
Thanks!

[nfs0619]

Hi, I’d recommend contacting our technical support at [email protected] and, if possible, including some photos or a short video of your setup, so they can help diagnose the issue in more detail.

I have four of these repeaters deployed and the battery level is dropping day by day in each of them. The first deployment was 30 days ago and the battery is now at 53% and 3.64V. I understand that it is winter here in Ireland with limited sunlight. How low will the battery go before the units switch off? Is there any upgrade path available?

[wpa-2]

Mine has been the same, its been up for for 3 days and lost over 20% but tis currently charging in low light so is a plus I guess.
The cold wont be helping the batteries much either.

[meshservicesireland-stack]

I'll let you know how mine goes. I'm curious to know at what percentage it will power off, and more importantly, if it will power itself back on again when we get sufficient sun.

had 2/3 days of sun and its recharged, pretty happy with that but will see how long term use is.
There is options to set in the meshtastic app when to shutdown during low battery but have not messed with it.
