Contribution description
15.2.2 Workaround
On the SX1262, during the chip initialization, the register TxClampConfig should be modified to optimize the PA clamping
threshold. Bits 4-1 must be set to “1111” (default value “0100”).
This register modification must be done after a Power On Reset, or a wake-up from cold Start
