To test BLE5.0 Long Rang mode based on AT firmware, you can use the following methods:
1、设置 BLE5.0 Coded PHY 模式
-
On the BLE client side, you can use " AT+BLESETPHY " to set the PHY mode of the current connection to Coded PHY mode.
-
On the BLE Server side, you can use the " AT+BLEADVPARAM " command to set the Coded PHY mode
2、增大 BLE RF Power
-
You can use the "AT+RFPOWER" command to set the BLE RF Power
AT+RFPOWER=,15,15,15
The following will provide the AT command sequence for testing BLE5.0 Long RangCoded PHY extended broadcast data transparent transmission using 2 ESP32-C3 devices based on AT firmware
Refer to "Bluetooth LE AT Example"
-
Bluetooth LE client read and write service characteristic value
-
Bluetooth LE server read and write service characteristic value
