13.4.9 SetLoRaSymbNumTimeout

This command sets the number of symbols used by the modem to validate a successful reception.

In LoRa® mode, when going into Rx, the modem will lock as soon as a LoRa® symbol has been detected which may lead to

false detection. This phenomena is quite rare but nevertheless possible. To avoid this, the command

SetLoRaSymbNumTimeout can be used to define the number of symbols which will be used to validate the correct

reception of a packet.

When the SymbNum parameter is set the 0, the modem will validate the reception as soon as a LoRa® Symbol has been

detected.

When SymbNum is different from 0, the modem will wait for a total of SymbNum LoRa® symbol to validate, or not, the

correct detection of a LoRa® packet. If the various states of the demodulator are not lock at this moment, the radio will

generate the RxTimeout IRQ.
