T-Halow is WiFi Halow, an optimized Wi-Fi solution for iot devices, which has a longer transmission distance while providing the same transmission power of 2.4GHz and 5GHz. T-Halow is equipped with the TX-AH module, which can operate in the 730M-950MHz band, the module can operate in the channel width of 1/2/4/8MHz, and can provide a physical throughput of 150 Kbps to 32.5Mbps.
T-Halow operates in two modes:
The two modes differ：
MODE1: Send AT command control to TX-AH via ESP32
TX-AH: Download huge-ic-ah_xxxxxxxxx_TAIXIN-usb.bin
ESP32: Download AP or STA
Notice：Debug using Type-C
MODE2: Send AT command control via micro-USB
TX-AH: download huge-ic-ah_xxxxxxxxx_TAIXIN-WNB.bin
ESP32: No firmware download required
Notice：Debug using Micro-USB

remark:
- The difference between the P series module and the earlier A series module is:
(1) The bottom left screen print of the P series is beginning with P, and the bottom left screen print of the A series is beginning with R;
(2) P series PIN4/5 needs power supply, A series does not;
- The module does not have a Shield by default. The name of the module with a shield is suffix-s, where S indicates shield.
