Hi,
I'm using PCA10040 board, There i connected the fuel gauge IC via TWI communication. There pca10040 will acts as master and fuel gauge IC will acts as slave.
While Read and write we are getting "NRF_ERROR_INTERNAL" error and hangs there itself. If i give some delay (like 100ms) for each read and write its working fine.
That same fuel gauge setup i connected to some other controller (Master), There also i'm accessing via TWI communication. There without delay i can able to read and write the values.
After that i probed both the setups (PFA),
setup 1 : PCA10040 (Master) - Fuel Gauge IC (slave)
setup 2 : Other Controller (Master) - Fuel Gauge IC (slave)
While comparing that, In Nordic setup, End of the each byte (after 9 clock cycles) SDA pulse goes high for some time. But in other controller not like that wherever data presents that time only it goes high.
Is that extra SDA pulse cause any issue ?
May i know why that SDA pulse goes high for some time in Nordic controller?
Thanks in advance,
