Will the ThinkNode M9 have a replaceable battery?

Jully — Wed, 02 Sep 2026 09:32:06 +0000

Sorry, this battery is not replaceable.

LR1262 LoRaWAN Node Board (CRT01269N), where is RP2040-USB-TTL.ino.rpipico.uf2 firmware file ?

Thinknode M3 MAC does not match label

tecsol — Sun, 12 Jul 2026 05:56:36 +0000

I have not been able to get the Thinknode M3 to connect to TTN. Scanning my LAN I could not find the M3. Connecting to a simple network it became obvious the M3 was registering with DHCP with a totally different MAC to the label. The G3 identifies itself as espressif.home. This gives me no confidence the Gateway EUI on the label is correct, or that the G3 even has the correct firmware installed. How can I verify this?

Why Thinknode M1/M5 has no GPS signal?

Jully — Thu, 07 Aug 2025 06:06:42 +0000

Please try the following.
1 Have you turned on the GPS switch?

2 In addition, the device must be placed outdoors to have a GPS signal. Is the device placed outdoors?

3 Please update your device to the latest firmware (both stable and unstable) and try again. The firmware update link is below.

https://flasher.meshtastic.org/

4 Maybe there is a mistake in the settings in the app. I suggest you try this: click Restore Factory Settings in the app, and then turn on the GPS switch on the device

5 If the problem still exists, please open the case and check if the antenna is loose or not fastened properly. If so, adjust the antenna and fasten it properly and try again.

Arduino kernel has changed and reset_lgw.sh shell script fails

pkirkham — Thu, 11 Jun 2026 12:09:28 +0000

I've recently purchased an LR1302 and hat for the Raspberry Pi. The reset_lgw.sh shell script fails because: echo "$SX1302_RESET_PIN" > /sys/class/gpio/export; WAIT_GPIO commands like the above are no longer supported with the stand…

How should solve the errors when using the LR1302 Gateway Module+HAT

Sun — Tue, 22 Oct 2024 08:58:16 +0000

Error 1
Note: chip version is 0x00 (v0.0)
ERROR: Failed to set SX1250_0 in STANDBY_RC mode
ERROR: failed to setup radio 0
ERROR: failed to start the gateway

Error 2
Note: chip version is 0x00 (v0.0)
ERROR: Failed to set SX1250_0 in STANDBY_RC mode
ERROR: failed to setup radio 0
ERROR: [main] failed to start the concentrator

If you encounter the similar error, make sure you're using buster first. They are not currently supported for use with bullseye and bookworm.

If you still have the same error using the buster version, it may be that the configuration is not completely correct. Try the configured image (https://drive.google.com/drive/folders/1LL42h4sYU6f8MrvipY9GQXjcZutR_NGr?usp=sharing) provided by Elecrow.

questions about thinknode M3 meshtastic version.

Jully — Thu, 14 May 2026 01:43:02 +0000

Question:
" I have a few questions about M3.
1. Can the case be opened to replace the battery?
2. Can the device be flashed to other systems like Meshcore or Meshcom?
3. Is it possible to activate an SOS button, like on the LoRa version?"

Answer:
"1. Can the casing be opened to replace the battery? --- No, the battery cannot be replaced.

Can this device be flashed with other operating systems, such as Meshcore or Meshcom? --- Meshcore is supported. Meshcom support is uncertain; you may check the respective platform for support.
Can the SOS button be activated like in the LoRa version? --- Sorry, The SOS function has been removed. "

Does ThinkNode G1 do full or half duplex on 8 channels, simultaneously?

Jully — Thu, 14 May 2026 01:38:35 +0000

Question:
"Does this do full or half duplex on 8 channels, simultaneously?
Is the firmware open source so I can modify it to customize it?

ThinkNode G1 SKU: CIL12302G"

Answer:
"The ThinkNode G1 is not open source. The ThinkNode G1 can receive from 8 channels simultaneously, but can only transmit from one channel. It is a LoRaWAN multi-channel half-duplex gateway, not an 8-channel full-duplex communication device."

Which regional channel plans does the Thinknode G1 support?

Jully — Thu, 14 May 2026 01:36:04 +0000

Response:
In addition to EU868 and US915, the G1 also supports AU915, AS923, KR920, IN865, and RU864. CN470 is not supported.

The hardware SKUs are not the same for all regions.
US915, AU915, AS923, and KR920 share the same hardware.
EU868, IN865, and RU864 share the same hardware.
Except for EU868 and US915, other frequency bands require users to develop/configure the software themselves.
