Not exactly the same thing, but I've been having reset problems with the BL0032. I'm working on a project that uses a lot of Bluetooth comms (I've rewritten the driver using interrupts). It's hard to keep the board up and running for long, it just keeps on rebooting. I can't quite remember, but I th...

Adding to my previous post. The firmware delivered on the board is 1.00, dating back from 2015. Current firmware available seems to be 1.13, I'll try updating to see, but I've gone and ordered some RN4678s, and I'll see how the updated version works.

Hi Benj, Thanks for your reply! The board is powered by a micro-USB cable that I've used for other development boards, and I've also changed boards (I have a few now). I've disconnected the BL0114 board, same result. I've now powered the system with a bench PSU. Still the same. I think we can elimin...

Hi everyone, I've received my BL0170 and I'm having fun. However, I did come across a little problem. When using my iPhone (using BLE Scanner) I can connect to my device, connect to the corresponding service, and then send data to the characteristic. My FlowCode app (using a BL0080) displays the str...

Thanks for your answer. Is there an ETA to that? For the time being, we can use UARTs, but I have another problem with UART, I'll post that separately.

I'm having difficulties when communicating between ARM components using I2C. My master, an F303, can communicate with a PCF8574AP, and blink lights to my hearts content. An ARM slave (F030 this time) can't receive anything. The bus does work, since the IO expander picks up communications, but the sl...

Hi there, I'm trying to create an SPI slave using an ARM (F030R8), but I have a compile problem: SPI Slave.o: In function `FCD_05311_SPI_Slave1__GetChar': SPI Slave.c:(.text.FCD_05311_SPI_Slave1__GetChar+0x2): undefined reference to `FC_CAL_SPI_Slave_RxByte_1' collect2.exe: error: ld returned 1 exit...
