Hello,I configured the s2-lp csma as follow: xCsmaPersistentMode = S_DISABLE xMultiplierTbit = CSMA_PERIOD_128TBIT xCcaLength = 1 cMaxNb = 2 nBuCounterSeed = 0xFA21 cBuPrescaler = 2 I set the rssi threshold at -82 dBm, If the channel is free, it list...

I have configured a GPIO as input to control the RX or TX state, is there a minimum time above the high level threshold to respect or exceed the VDD/2+0,3 voltage is sufficient ?Thank you,Andy Rochette.

Hello community,I configured the uart dma in my project based on the project example USART_TxRx_DMA_Init, and stuck in frame errors, one of the errors is the end of the string seems to be swapped.Sometimes there is no problem the end of the string is...

WakeupFromSleepFlag is set to 0 at the start of HAL_PWR_MNGR_Request() and WakeupFromSleepFlag is set to 1 only from startup_BlueNRG_LP.c :int __low_level_init(void) { /* If the reset reason is a wakeup from DEEPSTOP restore the context */ if ((...

Hello,Range should not be considerably shorter as the more the frequency decreases the more the range can increase. There will be a power issue if you use eval board, you should check for component datasheet (S21 parameter or return loss diagram) on ...
