Notes
CRITICAL UPDATE
Bootloader updates and various security rollup updates
Some teams have reported issues with radios not exiting the bootloader. Changes were made to address this particular bug.
Team Access Point behavior
Fixed bug when first setting a newly flashed radio as a Team Access Point resulting in a wireless subsystem crash, only resuming normal operation after a power cycle.

VH-109_1.2.8-01222025
Notes
CRITICAL UPDATE
This is a continuation of the flash corruption discovered in November of 2024.
Root cause failure analysis was completed and discovered an errant process writing to flash at a period of once every 30 seconds. In extreme circumstances, the NAND flash controller could glitch upon a power event (brownout or during power off), accidentally writing to critical regions of memory resulting in memory corruption that could disable the radio.

VH-109_1.2.7-01162025
Notes
Team Access Point behavior
Fixed bug when placing radio into "Access Point Mode" disabling the 2.4 GHz radio once a robot connects to the 6 GHz radio
Renamed the 2.4 GHz SSID when in "Access Point Mode" to "FRC-AP-XXYY-SUFFIX", making it more clear on which device you're connected to

VH-109_1.2.5-11032024
Notes
CRITICAL UPDATE
Flash memory corruption has been observed on a number of radios affecting the factory burned calibration and regulatory limits partition.
A mitigation has been developed addressing this potential corruption.
It is recommended that teams update to this firmware as soon as possible to prevent the radio from becoming inoperable without manufacturer support.

VH-109_1.2.3-10242024
Notes
Bug fixes
Fixed firewall regression
Port 1110 was disabled on the access points used at the 2024 FIRST Championship. This port was re-enabled for testing/practice use and was mistakenly included in AP firmware releases. This port is now disabled on the FRC and OFFSEASON variants of the access point firmware.
Fixed error display on radio configuration page when a bad firmware image is loaded
Fixed clearing of cache when a firmware upgrade attempt is unsuccessful
Fixed dynamic channel selection behavior resulting in occasional loss of connectivity in certain wireless environments (Bug reported by Tim Bennington-Davis)
Team Access Point behavior
Enabled 2.4 GHz SSID when in "Team Access Point"
Added Reduced Neighbor Report (RNR) information element (IE) to the 2.4 GHz SSID enabling client devices without standards-based FILS support to connect to the 6 GHz SSID (Behavior -not a bug - discovered by FRC Team 1425 and Tim Bennington-Davis)
Added firmware release in the footer of the Configuration page
Various UI improvements within the Configuration page related to loading of firmware
This release introduces two variants of the Access Point firmware, allowing teams to have a representative version of the official Access Point firmware used by FIRST
Offseason Variant
A fork of the official FRC access point firmware, without the configuration password set
Practice Variant
A fork of the Offseason access point firmware
Intended for use at practice fields without full FMS setups (DHCP server, etc), but still has access to a managed ethernet switch with VLAN tagging capability
Includes DHCP server on VLAN 10, 20, 30, 40, 50, 60, 70, 80, 90
Firewall is disabled
VH-109_AP_FRC_1.2.3-10242024
Includes FRC configuration password (not for public release)
VH-109_AP_OFFSEASON_1.2.3-10242024
Same as FRC image, without configuration password
VH-109_AP_PRACTICE_1.2.3-10242024
Same as OFFSEASON image, disables firewall and enables DHCP on all team VLANs
