M1 Firmware Release Notes

05/14/2022 - SenseCAP M1 OTA Update
May 14, 2022 - We released SenseCAP M1 firmware version 2022.05.13.0, which contains PoC related improvements.

Changes: 
1.Update helium miner to 2022.05.13.0
Notes: 
1.The firmware will automatically update, the hotspot owner does not need to do anything. Each firmware release will take a few hours to update all SenseCAP on the network, so please wait patiently to get your hotspot updated.
2.If your hotspot has updated to the new firmware and however not starting to sync after 30mins, you are free to do a reset block to manually sync the blocks. Here is the guide: https://docs.sensecapmx.com/m1/local-console/how-to-reset-blocks. If the buttons do not appear in the local console, please try to press CTRL + F5 or SHIFT + F5 on Windows, or COMMAND + SHIFT + R on Mac.
3.While syncing, we strongly suggest using the Ethernet Cable to connect internet. Poor Wi-Fi may cause slowing syncing and firmware OTA failure.
4.After updating the firmware, you may find the Hotspot blockchain height is Unknown in the SenseCAP Dashboard, it will back to normal in about 30mins.
5.It won't affect your hotspot's PoC activity if your hotspot is out of sync but the block height is higher than 1350664.

November 23, 2021 - We released SenseCAP M1 firmware version 2021.11.21.2 to improve network-wide block sync and snapshot ingestion on Hotspots with less memory.

Changes: 
1.Update Helium miner version to 2021.11.21.2
2.Fixed Blockchain height list.
Notes: 
1.The firmware will automatically update, the hotspot owner does not need to do anything. Each firmware release will take a few hours to update all SenseCAP on the network, so please wait patiently to get your hotspot updated.
2.If your hotspot has updated to the new firmware and not starting to sync after 30mins, you are free to do a reset block to manually sync the blocks. Here is the guide: https://docs.sensecapmx.com/m1/local-console/how-to-reset-blocks​
3.While syncing, we strongly suggest using the Ethernet Cable to connect to the Internet. Poor Wi-Fi may cause slowing syncing and firmware OTA failure.
4.After updating the firmware, you may find the Hotspot blockchain height is Unknown in the SenseCAP Dashboard, it will back to normal in about 30mins.
