Sends a packet periodically using BLE_LLD
I want to write a very simple program that sends a packet using BLE_LLD. For simplicity sake, for now, I prefer not using sequencer and put everything in the main loop.According to UM2804, I should be able to do that only using HAL interfaces. I star...
stm32wle5 SMPS oscillates when Vdd ~ 1.7V and prevents power ramp-up
I'm having a problem in a 1 gram tracker that uses an stm32wle5 powered by a 2.4V LTO battery and 4mW solar cell (through bq25504 energy harvesting chip). If the battery discharges below 1.7V ("should never happen"...) the solar cell cannot recharge ...
How to catch the RX timeouts and errors via the LmHandler registered OnTxData/mcps-confirm callback?
I am customizing the LoRaWAN_End_Node example for our purpose. My application is pretty simple, I send unconfirmed uplinks every 5 minutes after a successful join. On successful uplinks, I get MCPS-Confirm with a status of LORAMAC_EVENT_INFO_STATUS_O...
Resolved! Missing macro COPY_UUID_128 after changing UUID in CubeMX
Hi,When creating a custom template BLE app in CubeMX everything works fine while not changing the UUID of service1, it builds and compiles well. But if I change the UUID to my own UUID (with UUID 128 input type to full), after generating the new code...
