LORA-E5 Pin 24 (PB13/BOOT/SCK) needs to be pulled high #8

Closed dkadish closed 1 year ago

From https://wiki.seeedstudio.com/LoRa-E5_STM32WLE5JC_Module/#application-notes

The AT command firmware contains a bootloader for DFU and the AT application. The "PB13/SPI_SCK/BOOT" pin is used to control Wio-E5 to stay in the bootloader or jump to the AT application. When PB13 is HIGH, the module will jump to AT application after reset, with a default baud rate of 9600. When PB13 is LOW (press the "Boot" button on Wio-E5 mini/ Wio-E5 Development Kit), the module will stay in the bootloader, and keep transmitting "C" character every 1S at baud rate 115200.

PB13 needs to be pulled high so that it defaults to the AT application. There should be a jumper to pull it low as well.

This doesn't seem to be causing problems currently. Add a solderable jumper to correct this, if need be.

Test this with a jumper wire. Connect the broken out PB13 pin to GND and 3v3 and see if the jumper is necessary.

Solved with 856e9c33e074f8342c6f5b2cfc0530d1effd26fc. Still needs testing

Test confirmed. Tying to GND puts it into bootloader mode. Don't think we want this, but leaving the jumper there just in case!
